I have an astaro firewall. We brought email in house, an exchange server. Trying to get pop3 and imap over ssl to function. On the local lan it works fine. From outside in, it errors out.
Defined the service:
pop3ssl source tcp 1024:65535 destination 995
imapssl source tcp 1024:65535 destination 993
filter rule
any pop3ssl exchange server allow
any imapssl exchange server allow
nat rule
any external_int pop3sll none exchange server
any external_int imapssl none exchange server
The firewall is set up as a smtp relay from outside in.
Using one IP address on the external interface.
Any assistance would be welcome. Thanks. [:)]
