Hi all!
We want to try a new ISP, that is, we don't want to switch whats critical until we can confirm that the new provider is stable enough.
We are using 3 of 4 interfaces on the PIX 515e- outside, inside and a third (eth2 I believe). Third is a DMZ where some public servers are connected.
Would it be possible to connect the new ISP to the fourth interface (outside2) and
a) route some- not all- of the inside-outside traffic to "outside2". Outside -> dmz as now (old ISP) or b) route all of the inside-outside traffic to "outside2". Outside ->
dmz as now (old ISP) or c) Move old ISP to outside2 and let traffic from Internet to public servers stay on old ISP. Connect new ISP to outside and use this as normal (inside to Internet).
I hope it is possible to understand above explanation. The most important goal is: somehow test the new connection, but not yet change ip's for the public servers.
thanks for your time,
