I have my rb532 running v2.9.43 in a pretty straightforward firewall setup.
My isp gives me 'unlimited' public ip's, so I run my home network on public ip space
Now what I do is basically mark every packet going through the bridge and accept all incoming marked packets with my marking on it, also every established and related packet. Everythinge else goes straight to the binary waste bin. (is dropped)
This works flawlessly, but you should have guessed that I am having a small issue, why else should I write a posting on this board
My issue is that my msn messenger is not able to receive audio/video because I do not recognize that I would like this packets to go through my firewall. Because this setup is not initiated from my pc, but from the other side.
Does anyone have a suggestion ?
(UPNP does not seem to solve this problem, I guess because it is more intended for use behind a NAT router, not a firewall only)
