The only way i see to have external connection is to add a rule to my firewall teling it to redirect all POP and SMTP traffic to this internal server.
Is there a more secure way to do this? Is it secure to implement this scheme?
Yes, there is. Use an additional proxy for this. Have a look to the "rinetd" package.
and have a look at the Allow Deny options of rinetd, use if possible.
Why is this more secure than a packet-level port forwarder? I could imagine to use IPSec VPN; the clients could link into the internal LAN securely and work as if there were local. oki, Steffen -- Dieses Schreiben wurde maschinell erstellt, es trägt daher weder Unterschrift noch Siegel.
