I'm using PIX 515. One of segment connected to this Pix is network 10.12.187.0/24. On this network is router Cisco 1841, which connect networks 10.12.188.0/26 and 10.12.187.0/24.
The problem is that host 10.12.187.x, which has default gateway Pix, cannot ping any host on 10.12.188.0/26. This works only if I setup route on host 10.12.187.1, that network 10.12.188.0 is behind the router.
But when this host has default gateway pix, it doesn't work.
On Pix is route 10.12.188.0 255.255.255.192 (router IP address)
and router has default gw this pix.
Could you please advice me?
