hello,
at a customer location i'm working at there is an internet router with a /26 of public address space (say, 136.10.10.0/26) on the internal fast-ethernet interface. this fe is the gateway address, eg. 136.10.10.1.
now we want to put our PIX515E in between, _not_use_NAT_ and we're not able to change the config of the router for various administrative reasons... i know i can't do bridging until v7 but is there an alternative using statics?
will this work:
- assing a public ip to the outside interface;
- assign the 136.10.10.0/26 range to the inside interface;
- map all public ip's to the external interface using static (outside, inside) 136.10.10.x 136.10.10.x;
- create a 'route outside 0.0.0.0 0 136.10.10.1';
thanks for any help,
regards
Rutger

No, it will not work.
You really need a (FWSM) Firewall Switch Module or you have to wait for version 7.0 of FOS.
You will have a routing issue with your config using twice the same network on diffrent interfaces.
sincerly
