I still seem to be having problems with setting up my mail
server on a one to one NAT. Internally mail fails to connect via name
resolution, externally it works fine. Several people suggested I set up
internal DNS to resolve this issue but it does not seem to be working.
When I do an NSLOOKUP on my internal DNS it correctly resolve the name to the
internal IP address. (for testing it is the only DNS server I have)
However any mail program I try to send and receive mail from my internal
network mail will fail to resolve the name. I have shut down WINS so that
there is no conflict in naming.
I have also noticed when using an external DNS server that if
I try to send and receive mail from the internal network I get an ARP timeout
(Source) 0.0.0.0 (Destination) 19.168.155.98 (my internal IP for
mail) in my Sonicwall log files.
Anyone have any ideas.
Thanks for everyone's help on the list.
