Firewall/NAT

Hi,

I'm using m0n0wall 1.33 generic PC. The firewall is blocking SIP packets, no matter if I open port 5060 or forward it to my VoIP phone. Firewall log entries look like that:

15:18:10.352452 bge0 @0:25 b <IP of VoIP provider>,5060 -> 10.3.0.2,5060 PR udp len 20 32 IN bad NAT

I found this resolved topic, where Manuel Kasper wrote he fixed it: http://forum.m0n0.ch/index.php?topic=2423.0.

Is there something I'm doing wrong?

Thank you!

Edit: Could it be the Broadcom NIC? http://gnats.netbsd.org/30851

Hello!
Thank you for reporting this problem. I have similar problem where all PING-traffic works, but no TCP/UDP traffic.

What have cause the problem is the sucky sucky e-cheapo Lite-ON 82c169 PNIC 10/100BaseTX card, with driver (dc0).
Which have produced logs like

Code:

"@0:17 b 46.22.115.26,123 -> 192.168.20.100,123 PR udp len 20 76 IN bad NAT"

So after trying all sorts of log-reading, i found your post here. ==> Changed to an Intel (fxp0) NIC ==> Booted up. == Instant WIN.

The strange thing was: With m0n0 1.33 everything worked fine. But with snapshot 1.8.0b477 i stumbled over this problem.

Try a (fxp0) or (em0) card. Refer to FreeBSD 8 - hardware list for good NICs

Please let us know if it saves the day
