Title: Call of Duty - Modern Warfare Multiplayer
Post by: binaryanomaly on November 02, 2020, 06:18:40 pm

Hi,

I'm somewhat lost with getting "Call of Duty - Modern Warfare Multiplayer" to work.

Has someone managed to make it working and would be so kind to share the details?

I'm stuck with "NAT Type: Strict" and the game even failing to connect to the server.

Thanks

It works without me having to do anything on PC.

I did install the upnp plugin and open ports recommended but they did not seem to be used so I uninstalled.

I am working under the assumption that since my PC initates the traffic OPNsense is smart enough to let it go.

Cheers,

Hmm, it only works here if I allow all traffic from LAN to WAN - which is not preferred.
If I open ports selectively it doesn't work, no idea why...

hi, have you solved that issue? I have the same and I could not bring it to work...not with rules or UPNP

I wasn't able to make it work without opening up traffic from LAN to WAN completely.

When I only opened the ports as listed on the support page and also tried UPNP - it just wouldn't work.
Strangely I couldn't observe any drops in the fw logs.

Something's quite strange with CoD and OPNsense...

Guys,

There are guides to do this all over Reddit.

There are also guides on how to make the Nintendo Switch work (its all basically the same)

Protip: if someone did it on PFsense (everything has been done on PFsense) you can almost exactly copy what they did and make it work on OPNsense.

This is firewall outbound NAT (static port YES!!!!):

This is the alias I use for call of duty ports per google

These are my port forward rules

Last time I played it, call of duty showed I had NAT open, sometimes it shows up that my NAT is moderate (not sure why this fluctuates / assuming is COD).

It has never been strict since I set this up.

Remember google is your friend.

Cheers,

Tbh, I haven't tried since months...

But if this would have been a NAT issue how could "allow any traffic from LAN to WAN" solve it at all?
