Dynamic NAT Pool Problem

Small issue with dynamic NAT pools. In my screenshot I have two different networks.

INT f0/1 on CORP router and below are on 192.168.1.0 /24 network

INT f0/0 on CORP router and to the right are the 209.165.200.0 /24 network

ESW1 has VLAN 1 as 192.168.1.2 /24

PC1 and PC2 are 192.168.1.3 and 192.168.1.4

CORP router:

access-list 1 192.168.0.0 0.0.0.255

ip nat pool POOL1 209.165.200.2 209.165.200.4 netmask 255.255.255.0 (CORP and Internet IPs are 209.165.200.5 and 209.165.200.6)

ip nat inside source list 1 pool POOL1

ip nat outside facing Internet router

ip nat inside facing ESW1 and PCs

PCs and ESW1 can both ping default-gateway

CORP router can ping Internet INT and vice versa

** I cannot ping PCs to Internet INT with NAT pool settings properly. I receive:

"209.165.200.6 (Internet INT) icmp_seq=1-5 timeout"

Any thoughts to correct this? I had it working before.

Unless it is a typo your acl is wroing ie. 192.168.0.0 0.0.0.255 does not cover 192.168.1.0/24, should be 192.168.1.0 0.0.0.255
