Access Lists & NAT - Guru Support Needed.

Adam K.
Level 1
Level 1

Hi everybody! I have a network which I can connect to with via VPN and am able successfully reach my internal subnets. However, if I create access lists and NAT rules in order to allow a specific internal subnet/host out of the router, then I am not able to reach these specific internal subnets/hosts from the VPN connection. I am however, still able to reach the other subnets/hosts that I have not added an ACL and NAT rule for.

Please see the attached png file for a network diagram and a more visual description of the problem I am having.

I have also attached the configurations for the cisco router and switch.

What I want to achieve: Be able to reach any host/subnet in the internal network even if there is an ACL and NAT rule associated with it.

I would greatly appreciate any help/advice/pointers (anything) towards helping me diagnose and fix this problem.

Please let me know if there is anything more I can provide that can better explain the problem.

Thanks in advance!
