Hi All ,
This is our network diagram we plan to setup
| |-----------ISP1
| |
|---GW----|
| |
| |----------ISP2
| |
Inside NW DMZ Ouside
Out network connected to 2 ISPs and we plan to use CISCO PIX 515 as firewall to protect the DMZ.
I like to know whether it is possible to use only one CISCO PIX 515 as firewall .
I am not sure that it will work , please help me?
Thanks for any help

Hard to understand your diagram but if you have two Internet connections on the outside (load balancing or redundancy) then your gateway router outside has to do the load balancing. The PIX cant have two default gateways. Does that help?

If you have connections to two ISPs, this is a
router problem, not a firewall problem, because
the pix does not work as a router.
So, you have to mix the two ISPs network onto a
router directly connected to them (say, GW).
Then, what you have to do is simply to plug
your pix to the GW (and to the dmz, of course!)
and use a default network to the GW.
