ok.......
Problem is video conferencing. h323 specifically. I can't make connections through the router. The ACLs and the inspect statements are set right (supposedly). Other traffic (http, smtp, rdp....)flows without a problem.
Test lab:
Spare router ruining the same configuration file. With a laptop on either side running VC software. Same issue. No connection. What's odd and has to point to something is that: upon boot up of the router, once the interfaces come up, I can make VC connections between the two laptops. After about 15 - 20 min, it stops and I can't get through. Tells me the router doesn't like something or thinks it's malicious and stopping it.......just can't figure out what it is.
The conference units have public IPs that are NATed to private ones.
