using a PIX on a switched subnet?

bevaartcmg — Fri, 21 Feb 2020 07:35:02 GMT

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.
