Firewall for some but not others

[chaz]

Hi,

I setup my computer as autohost, with the tcp port 3453 open, and I have a fixed IP.

Some players can join my host, yet this morning Malsleizure said I had a firewall!

And when I tried to join Mals game, it was firewalled!

But when I connect to either my or Mals game using a different connection, both work fine!

Help.

do you use the same IP address?

This shouldn't really happen if all of the machines you are testing with are completely separate machines on the internet with unique IP addresses. If one or more are on the same network (i.e. behind the same router or similar) or potentially if you are using something like LTE/3G internet, it could be possible. Is any of that the case here? Specifically what do you mean by "different connection"?
