I am using one Cisoc router 1800 and one Sonicwall Firewall in my Network.
For accessing the internet and other web related services i am using Internet Lease line.
Now, I want to setup a new network wihich will be completely isolated from the current network but will use the same Internet Lease line.
The new setup will use the separate dedicated firewall for internet and NAT purpose.
My question is, Can i connect the new firewall with the cisco router?
As my Cisco router have two fast eithernet port out of which one is being used by existing firewall and second one i will use for the second firewall.
Is it possible if i give public ip address to my external interface of new firewall as well as internal interface of router and start doing all the NATing in the firewall to map the servers and other things.
(This i am already doing in my existing firewall)
will this be the good solution? if not what should be the ideal solution.
