I'm running a pix 515E for management purposes. I have several nets, one outside, and three inside. I've set up nat between them, since my inside0 has real ip addresses, and 1 & 2 has private addresses. This is working brilliantly.
My problem is a third private net.
It's located behind a 3750. I can reach it (172.18.18.0 -> 172.18.18.10 - loopback interfaces) from the 3750, (their directly connected in some of the interfaces) but not from the rest of the units (e.g. my supervisor server). I'm thinking of reaching these via nat in the pix. But no matter what I try, I just can't seem to reach the 172... addresses from my 90.x.x.x network. The mng vlan is terminated on a vlan interface in the 3750 router.
Any pointers would do me great;=)
