No Translation Group Found

[john.irizarry]

I am getting the following error from my ASA logs:

No translation group found for udp src inside:10.10.10.4/27351 dst outside:10.10.50.42/1129

outside 10.10.50.42 is the address given by my VPN pool. So I have a user on VPN trying to get his mail from the inside.

Strange thing is the VPN users have access to the inside network and all seems to be working fine.

The error suggests that a packet does not have a matching outbound NAT command rule.

Here are my NAT rules:

access-list nonat-in extended permit ip LAN 255.255.255.0 VPN 255.255.255.0

nat (outside) 1 0.0.0.0 0.0.0.0

nat (outside) 1 VPN 255.255.255.0 outside

nat (inside) 0 access-list nonat-in

nat (inside) 1 0.0.0.0 0.0.0.0

nat (dmz) 0 access-list nonat-dmz

nat (dmz) 1 0.0.0.0 0.0.0.0

What NAT would be missing?
