Problem Accessing Remote Hosts

roberts.geo

Level 1

I've setup our Pix 515's to allow remote access. Locally we are in the process of migrating users between 2 networks. We can access the remote hosts from the old local network, but not from the one we are migrating to. I don't know if it has something to do with the ip addressing scheme. We are moving from a 192.168.0.0 255.255.255.0 subnet to a 10.224.0.0 255.255.0.0 subnet (yeah, I know, I just inherited this mess). Here is the config from the PIX:

interface ethernet0 auto

interface ethernet1 auto

nameif ethernet0 outside security0

nameif ethernet1 inside security100

nameif ethernet2 intf2 security4

nameif ethernet3 intf3 security6

nameif ethernet4 intf4 security8

nameif ethernet5 intf5 security10

There are no errors in the client log.

Can anyone tell me what I'm doing wrong here? Thanks in advance!

C'mon somebody must have an idea

Ok, I've been digging through the posts and will try the following. Adding

crypto isakmp nat-traversal

and changing the nat pool to something in the 172.x.x.x network.

I'll post something after I've tried that.
