Asymmetric NAT rules

[ppavlovich]

Hi all -

I have a 5510 that acts as a firewall for my location. My internet router lies outside of this and I am trying to TACACS to it, however I get an Asymmetric NAT rules matched for forward and reverse flows error when trying. I am seeing hits on my permit ACL statement to allow this to happen, however, it cannot reach back to me. Any ideas?
