Need some help on this one guys...
The crime scene is as follows..
Dual ISP links:
Cable Modem, using PPPOE (DHCP assigned external IP) ppp0 via eth0 213.17.94.x
ADSL, using STATIC IP eth2
Internal Network eth1
Internal E-Mail Server to be portforwarded from ADSL Connection (eth2)
Image:EigerStein2Beta PPPOE version by K. Hardley
Mistary to be solved:
I need to know how to have both devices be configured as External Interfaces, so that the can be proteceted by the Firewall Script.
Need to know, how to let the DHCP script only assigned a DHCP address to the Cable Connectoin and not the ADSL Connection
Need to know, how only let incomining SMTP and POP3 packets from the ADSL connnectoin be portforwed to internel e-mail server, and SMTP and POP3 packets coming in from the Cable Modem be denied....
That's about the basics, any nice suggestions would be also welcomed..
thnks
