Nope. I changed to the gateway address to point to the new server. As I
stated before, I get a firewall session on the sessions window. Just no
PoP3 download or SMTP. However if I make it a firewall client then we get
PoP3 download, still no SMTP.
We even opened up all the ports on the packet filter and protocol rules.
