Hi there,
looks like that I had an issue with an VPN client behind my m0n0wall.
udp 500 and 4500 works fine, when the connections is launched, but then UDP (no ports) will be blocked.
In my log file I got UDP blocked, no ports. There is only one client in my LAN using this particular vpn client.
The client is configured to use IPsec over UDP.
Maybee I'm wrong, but my default configuration is
Proto Source Port Destination Port Description
* LAN net * * * Default LAN -> any
So I expect that this should work.
M0n0 firmware is most recent (1.231).
Thanks in advance for any hints
Thomas
Unfortunately it is working fine on my D-Link-524 I normaly use as Accesspoint and Switch only

Update: After configuration of an openBSD based mini system (4.1-stable) it is also. Didn't have the time to check with the lates m0n0 release. I'll do as soon as I have some spare time!
