Hi,
I am trying to do Auth-Proxy with a Cisco router running 12.4(7) and Secure ACS Solution Engine 3.3.3.11.
The router is configured as
+++++++++++++++++++++
aaa group server tacacs+ aus-nac-group-tacacs
server-private 10.190.99.26 key xx
ip tacacs source-interface GigabitEthernet0/0.99
aaa authentication login default group aus-nac-group-tacacs
aaa authentication login telnet group tacacs+ local
aaa authentication eou default group aus-nac-group
aaa authorization exec default group aus-nac-group-tacacs
aaa authorization exec telnet group tacacs+ if-authenticated
aaa authorization commands 1 telnet group tacacs+ if-authenticated
aaa authorization commands 15 telnet group tacacs+ if-authenticated
aaa authorization auth-proxy default group aus-nac-group-tacacs
aaa accounting exec default stop-only group tacacs+
aaa accounting commands 15 default stop-only group tacacs+
aaa authorization auth-proxy default group aus-nac-group-tacacs
ip auth-proxy name test-auth telnet inactivity-time 5 list nac-test-trigger_acl
++++++++++++++++++++++++
On the secure ACS a new service is defined as "auth-proxy".
In the user-profile the auth-proxy box is checked and Custom-Attributes are defined as
+++++++++++++++++++++++++++
priv-lvl=15
proxyacl#1="permit tcp any host 198.133.219.27"
+++++++++++++++++++++++++++++
However when user initiates a connection, the user authentication succeeds but Authorization fails and the following message is shown on ACS
++++++++++++++
Service denied
service=auth-proxy protocol=ip
++++++++++++++
Any idea what could be going wrong here ?
Thanks,

I had the same problem. You can try to change the custom attribute from
proxyacl#1="permit tcp any host 198.133.219.27"
to
proxyacl#1=permit ip any host 198.133.219.27
If that succeeds, you can begin finetuning the access--list until it does what it is supposed to do.
Hope it helps.

I will give it a shot. Though exactly the same ACL format works when i use RADIUS protocol instead of TACACS+..!
