If you are using home internet as a source of residential IP for one account or anti-detect profile, routing all traffic through a proxy on the router is a bad idea: it slows down the speed for all other devices in the house, including smart TVs, family members' phones, and work laptops. In this article, we will discuss how to isolate proxy traffic only for one device or application without affecting the rest of the network.
Why Allocate a Proxy for One Device
This task often arises for those who work with multi-accounting: an arbitrageur sets up a Facebook Ads or TikTok Ads account and wants one specific account to access through a home IP that appears as "clean" as possible — with history, provider geolocation, and static behavior of a real user. An SMM specialist can similarly allocate one client profile in Dolphin Anty or AdsPower under a home IP while the other 29 accounts operate through residential proxies from a provider.
The point is not to route the entire house through a proxy server, but to ensure that only one application, browser profile, or physical device (for example, an old phone dedicated to farming) accesses the internet through the desired route — SOCKS5, HTTP proxy, or VPN tunnel. Other devices continue to operate directly through the provider at full speed.
This is especially relevant for marketplace sellers who monitor prices on Wildberries or Ozon from one home parsing server, not wanting the parsing to "consume" the bandwidth for the rest of the family or office.
Why a Proxy on the Whole Router Slows Down the Network
When a proxy or VPN is set up at the level of the entire router (through a built-in VPN client in the firmware or global proxy in DNS/NAT), all traffic from all devices starts going through an external server. If this is a residential proxy with limited speed or a tunnel with high latency, everyone suffers: YouTube videos start buffering, Zoom calls drop, and loading pages on Avito takes seconds instead of milliseconds.
An additional problem is that most consumer routers (regular models from TP-Link, Xiaomi, D-Link) physically cannot handle traffic proxying at the kernel level with encryption: the router's processor is weak, and under full network load, NAT speed drops even without a proxy. Adding an encrypted tunnel for all packets multiplies the CPU load several times.
Therefore, the correct approach is not to touch the default routing but to specifically redirect traffic from a particular MAC address, IP, or VLAN. Such solutions are available on routers with Keenetic OS, OpenWrt firmware, as well as on ASUS models with Merlin and MikroTik RouterOS.
Method 1: Separate VLAN or Guest Network
The simplest option without manual route configuration is to create a separate Wi-Fi network (guest or VLAN) and connect only the device that needs the proxy to it. Most modern routers (Keenetic, ASUS, Xiaomi AX) support a guest SSID with an isolated network segment.
Step-by-step in the Keenetic firmware:
- Access the router's web interface → "Network Segments" section → create a new segment (for example, "Proxy Zone").
- Bind a separate Wi-Fi SSID or a specific LAN port to this segment.
- In the "Connection Policies" section, specify that all traffic from this segment should go through the VPN/proxy connection (Keenetic supports SOCKS5 and OpenVPN client at the policy level).
- Connect the device (phone, laptop with an anti-detect browser) specifically to the new network.
On ASUS with Merlin firmware, a similar logic is implemented through "VPN Director" — there you can specify specific IP addresses from the local network that should be routed through the VPN client, while all other traffic bypasses it. Other devices do not notice any changes in speed at all.
Method 2: Policy-based Routing by MAC/IP
If the guest network is not enough (for example, if you need to redirect traffic not for the entire device but for a specific application), policy-based routing is used — routing rules based on the source IP or MAC address.
On MikroTik routers, this is done through a combination of Mangle and routing tables: you mark packets from a specific device IP and direct them to a separate table, where the default gateway is the proxy server or VPN tunnel. Other traffic goes through the standard provider route.
A simplified version of the same approach is available in the Keenetic web interface in the "Policies" → "Additional Rules" section: there you can specify a static IP for the device in the local network and bind it to a specific internet connection (for example, to a configured SOCKS5 proxy). This takes 5-10 minutes and does not require a console or scripts.
Tip: Assign a static IP to the desired device through DHCP reservation in the router settings — otherwise, upon reboot, the device may receive a new address, and the routing rule will stop working.
Method 3: Mini Proxy Server on Raspberry Pi
The third option is to not touch the main router settings at all, but to set up a separate small server (Raspberry Pi, an old router with OpenWrt firmware, or a mini-PC) within the local network that acts as a SOCKS5 proxy gateway only for the devices connected to it.
The scheme is simple: the Raspberry Pi connects to the main router via Ethernet, sets up its own Wi-Fi access point (or a second LAN port), and all devices connected to this point automatically go through the proxy/VPN tunnel configured on the Pi itself. The main home network does not notice this — the load is placed only on the small server, not on the main router.
This approach is convenient for agencies that keep 5-10 devices for account farming in a separate room or on a rack: one Raspberry Pi or mini-PC with Ubuntu Server serves this entire group without affecting the office network with employees' work computers.
Comparison of Methods
| Method | Complexity | Firmware Required | Suitable For |
|---|---|---|---|
| Guest Network / VLAN | Low | Keenetic, ASUS Merlin, Xiaomi AX | 1-3 devices |
| Policy-based Routing | Medium | MikroTik RouterOS, Keenetic | Point control by IP/MAC |
| Separate Mini Server (Pi) | Medium-High | Any router (Pi operates separately) | 5-15 devices, agencies |
Risks of Home Schemes for Arbitrage and SMM
A home IP through your own router only partially solves the task of "looking like a real user." Multiple subscribers (CGNAT) can be on one IP with the provider, the IP may be blacklisted due to past actions of neighbors in the subnet, and most importantly — it is static: if an account on Facebook Ads or Instagram ever gets banned on this IP, you cannot quickly change it without rebooting the router and waiting for a new allocation from the provider.
For one test account, this is acceptable. But if the task is to manage 20-50 accounts or maintain a pool of devices for TikTok Ads, a home scheme with one static IP does not scale: you are physically limited by the number of available home connections and lines.
Another nuance is that providers often block or limit speed upon detecting atypical activity on the line (constant requests to advertising APIs, parsing marketplaces), which can lead to complaints from the provider or temporary restrictions on the entire house, including devices not involved in farming.
Alternative: Ready-made Residential and Mobile Proxies
If the task is not a one-time test but regular work with multiple accounts, it is wiser not to build a scheme with VLAN and policy routing, but to use ready-made residential proxies — they provide real IPs from home providers around the world, with rotation and without the risk of getting your line banned by your internet provider.
For tasks where maximum "liveliness" of the IP is important — for example, farming Instagram or TikTok Ads accounts — mobile proxies are often chosen: they use IPs from cellular operators, which platforms are extremely reluctant to block due to the general pool of subscribers at one address.
For monitoring prices on Wildberries, Ozon, or parsing Avito, where speed is important rather than disguising as a "live" user, data center proxies are sufficient — they are faster and cheaper, and the parsing task does not require the home reputation of the IP.
This approach eliminates the very problem of "slowing down the home network": the traffic of accounts and parsers initially goes not through your line, but through an external pool of IPs that you configure directly in the anti-detect browser (Dolphin Anty, AdsPower, GoLogin, Octo Browser) at the profile level, without interfering with the home router at all.
Setup Checklist
- Determine which device/application should go through the proxy and write down its MAC address.
- Assign a static IP to the device through DHCP reservation in the router settings.
- Choose a method: guest network (simple), policy routing (specific), or a separate mini-server (for a group of devices).
- Check the speed on other devices at home before and after the setup — it should not change.
- Test the IP through a geolocation and connection type checking service before creating a real advertising account.
- If the task scales to 10+ accounts — switch to ready-made residential or mobile proxies instead of the home scheme.
Conclusion
Allocating a proxy for one device in a home network is quite feasible without losing speed for others: it is enough to use a guest VLAN network, policy-based routing by IP/MAC at the router level (Keenetic, ASUS Merlin, MikroTik), or a separate mini-server like Raspberry Pi. This approach works well for one or two test accounts but has scaling limits and risks associated with the static nature of home IP and provider policies.
If you plan to manage more than a few accounts or regularly parse marketplaces, we recommend not tying yourself to a home line but trying residential proxies — they provide the same effect of a "live" IP but without risks to your personal network and without limitations on the number of simultaneous connections.
