PIX outside interface multiple IP addresses

Hi,

Is it possible to assign 2 or 3 IP addresses to PIX outside interface? (Just like secondery IP address in case of router FE port.) Is this feature available in new (7.0) os ?

Regards,

Sunil

No . It is not possible. You can create VLANs if required to split up the subnets on the outside interface, but cannot use secondary IPs.

Hope this helps.. all the best.

Thanks Raj.

Is it advisable to use same PIX firewall for 2 different ISP's? (By configuring other available FE for 2nd ISP while outside interface for 1st ISP)

Sunil,

If the ISP links terminate on two different routers, you cannot have one firewall managing the show. YOu need to have a firewall for each router/ISP, since firewalls can have only one default route, unlike routers.

If both the ISP links terminate on the same router , you can manage connections through them using the same firewall. create nat/.static statements based on the IP addresses of each of these ISPs.

hope this helps. rate replies if found useful...
