Most people who search for a Call of Duty proxy want one of three things. They want the right value for the proxy server field on a console, a fix for lag, or to know whether Call of Duty bans an IP address. This page answers from Activision texts and the PS4 user guide, read on 28 September 2026. The short answer: the console field is for networks that need a proxy, and the game runs on UDP ports that Activision lists. Its terms bar connections through tools it has not approved. Its penalties land on accounts and devices, and its policy names no ban on an IP address.
The proxy server setting on a console
The PS4 user guide covers the setting on its page about setting up an Internet connection. With Easy setup, the console does the work: "When you select [Easy] and follow the on-screen instructions, setup is automatic." A proxy server is one of the extra settings that some networks need. For those, the guide says to select Custom and to "Refer to the information from your Internet service provider and the instructions supplied with the network device in use".
So the value comes from your provider or your network, not from Call of Duty. If nobody gave you a proxy address, there is nothing to enter. Our guide to the proxy server on PS5, PS4 and Switch walks through the screens.
For lag and failed matches, Activision points to ports and NAT instead. Its Port Forward and NAT FAQ describes three NAT types: Open, Moderate and Strict on Microsoft or PC, and Type 1, 2 and 3 on Sony. The stricter types limit which consoles and PCs yours can connect to. In the words of the FAQ, "an Open/Type 1 NAT will provide the best connection quality".
The ports: Call of Duty plays over UDP
Activision lists the ports of each Call of Duty game in an article dated 3 February 2026. For Black Ops 7, Black Ops 6, Warzone, Modern Warfare III and Modern Warfare II, the UDP ports are these.
| platform | UDP ports |
|---|---|
| Steam | 3074, 27015, 27031-27036 |
| PC | 3074, 3478, 4379-4380, 6112-6119, 20500, 20510, 27000-27031, 27036, 28960 |
| PlayStation | 3074, 3478-3479 |
| Xbox | 88, 500, 3074, 3544, 4500 |
Each platform has TCP ports as well. Call of Duty: Mobile has its own row: TCP 80, 443, 65010 for the lobby and 65050 for chat, and UDP 7500 to 8000.
UDP matters for proxies. The SOCKS5 standard, RFC 1928, gives the proxy a way to carry it. Its UDP ASSOCIATE request "is used to establish an association within the UDP relay process to handle UDP datagrams". We do not route a match through a proxy, for the reasons in the next section.
What the Activision rules say
Two texts set the rules. The Activision Terms of Use are dated 5 September 2025. The Call of Duty Security and Enforcement Policy is dated 31 July 2026. The terms list what you may not do "under any circumstances", and three of those lines matter here.
- "intercept, emulate or redirect the communication protocols used by Activision in any way, for any purpose".
- Create or maintain an "unauthorized connection to the Product", including "any connection using programs or tools not expressly approved by Activision in writing".
- Use "cheats, automation software (bots), modded lobbies, hacks, mods or any other unauthorized third-party software".
The policy then defines the infractions. Spoofing is "Any attempt to hide, disguise, or obfuscate your identity or the identity of your hardware devices". Circumventing Security is "Any attempt to circumvent our security systems". Forcing the game through a proxy means redirecting its connections with a tool, which is what these lines describe.
The terms also rule out trading accounts. Activision "does not recognize the transfer of accounts", and the sale of accounts or log-in information is among the barred uses. The policy covers Call of Duty titles from Modern Warfare (2019) on, and the console and PC titles released after it. The Call of Duty: Mobile site links to the same Activision Terms of Use.
Bans land on accounts and devices
The policy says where its penalties land: "Active enforcements are tied to Activision accounts and are implemented across all devices linked to the account." The account holder answers for everything on the account. In the words of the policy, "We apply penalties no matter who was playing at the time."
| penalty | lands on | appeal |
|---|---|---|
| temporary ban | the account | no |
| permanent ban | the account, and can apply across titles | yes |
| hardware ban | the device, not the account | no |
| limited matchmaking | the account and its party | not named |
The policy names no ban on an IP address. The only addresses it mentions belong to the IP flooders on its list of banned tools. So a new address does not lift any of these penalties, because each one stays with the account or the device.
Detection does not rest on the address either. On PC, the listed titles run the RICOCHET Anti-Cheat kernel-level driver for all players. Activision says the driver "monitors and reports applications that attempt to interact with protected Call of Duty titles".
Lag, lobbies and floods
For lag, the Activision route is ports and NAT, as above. Some proxy sellers publish tests that show Warzone ping falling through their proxies. We did not run one, and routing a match meets the terms quoted above.
Searches also ask for VPNs that find easier lobbies. We do not cover that. The clause on spoofing and the clause on unapproved connections are the rules that apply to it.
Some players are knocked offline by a flood of traffic. Activision treats that as a breach by the attacker. The terms bar "launching a denial of service attack", and the policy lists "IP flooders, and lag switches" among unsupported tools. The anti-cheat overview asks players to report what they meet in game. It also strongly recommends two-factor authentication for the account.
What the Activision websites showed our server
We sent plain requests from our server in St. Louis on 28 September 2026, with a browser user agent and no JavaScript. Every public page we asked for answered.
| page | answer |
|---|---|
| the Call of Duty home page | HTTP 200 |
| the Warzone page | HTTP 200 |
| the Call of Duty: Mobile page | HTTP 200 |
| Activision Support and the policy | HTTP 200 |
| the Activision Terms of Use | HTTP 200 |
So the websites did not turn away our data-center address. The rules above apply in the game and on the account, where we did not test.
If you use proxies for other work
Nothing on this page routes Call of Duty through a proxy, because the terms rule out redirecting its connections. Our page on free proxies for Call of Duty tests free proxies against the official site. For other games, see our pages on proxies for Counter-Strike 2 and proxies for Valorant. For the basics, see what a residential proxy is, whether free proxies are safe and how to check if a proxy is working. Our free proxy list and proxy checker cost nothing. Our residential, ISP and mobile proxies are on the pricing page, and residential traffic starts at $0.44/GB.
The limits of this page
We did not play Call of Duty, log in, or route the game through a proxy. We made plain requests from one server in the United States. The penalties come from the policy, which covers console and PC titles, so the Mobile facts on this page are its ports and its terms. Autocomplete also offers "call of duty proxy war" and "mtg call of duty proxy". This page is about network proxies only. It is due for a check by 28 December 2026.
