Internet Connection Firewall and multi-homed NIC

[Guest]

Hi

I´ve got the following problem

PC running XP Pro with one NIC and two IP-Adresses bound to that NIC. I cannot use just one address due to some non-MS services running on that machine

I enabled the ICF for that NIC and added manual entries to the services tab with different IP-Addresses/DNS-Names for the two IP-Addresses bound to the NIC

eg

193.111.111.1 TCP-Port 111
193.111.111.2 TCP-Port 111

I cannot make any connections to the ports bound to the secondary address. I allowed an ICMP echo. It works on both IP-Addresses

I also tried to bind the needed port to 127.0.0.1. Still no success

Is there any way to configure it like this. I would like to gain the additional security of the ICF, although using another firewall on a seperate machine

Hi J.,
Unfortuantly ICF at this time does not allow this functionality. Its either
all or nothing on a card, it is not configurable by bound IP address.
