	i install a firewall and natd with 2 NICs (one for public and
other for internal network), iam mapping (a STATIC map) with natd from 1
public ip to one internal ip address, the ip came to the WWW server and
e-mail server, all the rules are working (i can see the WWW server from
the outside and i can send and recived e-mail), but i dont know how to
establish the rule for permit from a specific network (public network) to
have pop access (for check their e-mails across other palataforms (like
w*ndows). 

the ips:
	my public ip address: 208.195.117.130
	mapped to my internal ip: 192.168.1.2

can you help to me in establish the rule for permit the pop3 port access?
i only need to permit the network 208.195.117.0 (mask 0xffffff00) 
or can you indicate to me where can i find some rule samples for this?

Thanks in advanced
Alejandro Galindo
