bardosy 158 Posted January 30, 2019 I tried to port forward to create a server. I want to open 2302-2306 in both TCP and UDP. But unfortunately my router told I cannot use 2302-2303, because they are reserved ports to the router. Am I right when I admit I stuck and it is impossible to solve this problem (except buy an other router) ? Or maybe do you have some trick to solve this?

BvB1 23 Posted January 30, 2019 You can specify a different port, in the server launch/command line you would use -port= xxxx . BIS wiki on servers Or if for whatever reason you want default ports can try disconnecting any other devices to see if one of them are using the port (smart TV, wireless printer, phone, tablet etc). 🙂 1 Share this post Link to post Share on other sites
bardosy 158 Posted January 31, 2019 Thanks! I didnt specify the problem, but I mean not dedicated server. I want to start a server in my arma client. Can I add this -port=xxxx in the launcher to the game (not a dedicated server)? Unfortunately I have no any device use this ports, so it's the router itself (TP-Link) and official answer is to buy a new router 😉 Probably I will...

BvB1 23 Posted January 31, 2019 I'm not sure if the option in the arma launcher will work for listen/client server, but under parameters, all parameters, host, there is a server port option, which is the -port command run via the launcher. Additionally, in game if you do the multiplayer, server browser, host route, you can specify a port there as well. I've never tried doing that with a client/server, but so far as I know one/both of those routes should work. :) Share this post Link to post Share on other sites
beno_83au 1369 Posted January 31, 2019 You could ask on a networking forum or something similar. I'd have no idea if a routers reserved ports can be changed though. Share this post Link to post Share on other sites
bardosy 158 Posted February 6, 2019 Thank you guys for the answer. I bought a new router and I could port forward. So everything is fine. Share this post Link to post Share on other sites

Very much the same, no need for different firewall rules. 2302 -2306 would be perfectly fine. Share this post Link to post Share on other sites

The other is only UDP. https://community.bistudio.com/wiki/Arma_3_Dedicated_Server#Port_Forwarding Arma doesn't need any TCP forwards, so it also shouldn't break anything if you also forward TCP. 1 Share this post Link to post Share on other sites
maquez 141 Posted March 21, 2019 security reasons .... portrange 2302-2305, 2x02-2x05... UDP Steam related ports port 2306, 2x06... UDP Battleye related port (different server location) do not open any non needed ports "TCP" (security reasons too) sure you could open the entire portrange from 0 up to 64738 TCP/UDP but this would be a very stupid idea Getting a Close Look at Firewalls what is a firewall (do work as a Cyber Security Consultant) 1 Share this post Link to post Share on other sites
