Going bald over a Cisco ASA 5505

I'm rapidly loosing my hair over what should be a simple ASA 5505 configuration.  I can't get smtp (port 25) traffic from the Internet to pass through the firewall to the inside host. The inside servers and workstations can access the Internet just fine but nothing from the outside can come in even through I think I've configured the access rules and NAT rules properly. Any help would be greatly appreciated.  Below is the sh config output:

The firewall configuration looks good.  Is your SMTP server's default router pointed to  Are you able to telnet to port 25/tcp on from the LAN?  Lastly, is the SBS firewall active on COPSrv01?

I don't quite understand your question about the smtp server's default router being pointed to

I am able to telnet to port 25/tcp on from within the LAN

The SBS firewall is turned off.

When I try to telnet from the outside to port 25/tcp on the outside interface I get these messages in the log:6      Jan 05 2010      09:46:41      302013      55546      COPSrv01      25      Built inbound TCP connection 1872 for outside: ( to inside:COPSrv01/25 (

Thanks for your help

It looks like the COPSrv01 server isn't responding to the inbound request.  What do you get when you run an "ipconfig" command on COPSrv01?

 inspect esmtp
jimsquAuthor Commented:
Turns out it was a stupid Micro$oft thing.  They don't, (in windows 2003) properly support multiple default gateways.  I had the server configured so that it should have responded to the default GW for the same subnet but it wasn't doing it.  The responces were always going to the same default GW which was in the wrong subnet.

The fix was to completely disable the (old) primary IP address and GW and only use the new ones that were behind the Firewall. Then things worked like they should.
Jody LemoineNetwork ArchitectCommented:
So the problem *was* that the COPSrv01 server wasn't responding to the inbound request.  This due to its not using the correct default router, which would have been revealed by the "ipconfig" command as I suggested.
Istvan KalmarCommented:
did you tried fixup on ASA?
Jody LemoineNetwork ArchitectCommented:
The problem was solved by the author by investigating the server configuration as suggested by "It looks like the COPSrv01 server isn't responding to the inbound request.  What do you get when you run an "ipconfig" command on COPSrv01?"  I recommend that this solution be accepted.
