Server 1 has gwia, a domain and a post office with a private ip address

Server 2 is BM3.8 running on 6.5….We have 2 nics one public one private
I have nat running with a public address pointing to the private ip of
Server 1… NAT Implicit Filtering is disabled

With Filters on we get no mail with filters off we get mail

What filters do I need to add to get mail to gwia? I have Mr. Johnson’s
book and have the SMTP to GWIA filters add but it is still not working…

Thanks, D
