Simple Port Forward for Steam

RouterOS Beginner Basics
1

Hello everyone well my question is simple i have been trying to simple port forward some ports so Steam could work but i have no luck at all.

The ports required for steam are these

UDP 3478 (Outbound)
UDP 4379 (Outbound)
UDP 4380 (Outbound)

I called my ISP provider but they dont know anything about these issue and they keep telling me that the ports are open but they are not. Please help me with these issue i have read alot in the forum but i just cant find the correct answer for these. Btw im ussing Mikrotik for connection to my ISP antena and another router for wireless connection in my house. The only rule i have its these.


Here is the export of my firewall config. Hope you guys can help me with these im not experienced with these kind of routers thanks!

If you are talking about the STEAM client the ports seem different.

At the moment your firewall shows no special NAT entries so what have you tried?

well the ports that i tryed to enable via nat are these


Steamworks P2P Networking and Steam Voice Chat
UDP 3478 (Outbound)
UDP 4379 (Outbound)
UDP 4380 (Outbound)

im not sure whats the exact method to enable them but i tried alot of the codes given away at the forums but none of them seems to be working, can anyone please teach me or tell me what should i do to enable these ports?

Is there any reason, why those ports are listed here:

/ip firewall service-port
set h323 disabled=no ports=3478,4379,4380

?

Because they sure aren’t there in clean install.

No particular reason that was one of my tryouts to unlock the ports that i need

Remove them from there. I’m not sure if it can break things (I tend to believe it could), but it definitely does not help anything, so there’s no reason to have them listed there.

Then, looking at your config, you have only one active firewall rule, the masquerade one (NAT). It means your router does not block anything, because by default, everything is allowed. For testing, you can add logging rules, to see how packets enter and leave the router:

/ip firewall mangle
add action=log chain=prerouting dst-port=3478,4379,4380 protocol=udp
add action=log chain=postrouting dst-port=3478,4379,4380 protocol=udp

You should see packets coming in from LAN interface and leaving though WAN. If you don’t see anything, you can have the communication blocked by firewall on your computer.
