Hello Johan,

 

When we configure

 

ip inspect name test udp router-traffic  

 

and apply it outbound on s0/1/0  ,  this matches the udp traffic that is
geneated by the router and creates dynamic openings for the return traffic.
In this case, when the router generate NTP requests, sessions are created in
the router and the returning Response is allowed , despite the interface ACL
blocking it.

 

Cheers,

TacACK
