Another NAT question

Hi, I have been trying to solve this problem all afternoon. I know it is a simple NAT issue but I just can't figure it out.

Just installed a ASA 5505 for a new PtP fiber connection to a customer. We are extending the customers LAN to the ASA over fiber. The EVV  LAN side of the fiber is Now the EVV LAN location has a 2nd location connected by a PtP T1. The Remote end of the T1 is The T1 has a router in EVV with a GW of

All works well evcept when people on the remote end of the T1 try to connect to servers in EVV on I get an error on the ASA

3 Aug 21 2010 13:58:05 305006 53   portmap translation creation failed for udp src PtP: dst PtP:

I know this is a NAT problem since I must route the traffic back out the ASA LAN GW of which is the same interface it arrived on.

Thanks if anyone can help oit.

Re: Another NAT question

Thanks I found the solution. I used the VPN wizard to make the VPN and made a mistake. The mistake left some incorrect NAT runles in the config. After reviewing the comfig some more I found and deleted.

Thanks for your responce.
