[nos-bbs] linksys router

[Kerry Smith]

Hello All,

Something else to remember when using the Linksys routers is that they
NAT EVERYTHING!  If you your machine on the dmz, and it has two ip's,
such as 44.x.x.x and 192.168.x.x, the 192 ip will get have nat applied along with your 44.x.x.x addy.  When smtp attempts to send mail to your
machine, it's attempting to make the connection to the 44.x.x.x, the 
jnos machine responds out as 44.x.x.x but the linksys will do it's magical
nat and come out as your public ip.

Not sure if this is what your hitting or not.  I missed the first part of
this question, so sorry if this is way off topic.
