Has anybody got a clue how to block ICMP redirect messages on a Teleworker Server?
Interesting problem. I have a TW in server/gateway mode. (actually behind a firewall - NO NAT!) A phone on the same subnet calls through the TW Server to any internal phone. Hangs up after a few minutes ~2-15.
Now, get this, only a problem on internal calls. Never on exernal. Same 3300, MXe.
A sniff shows a ICMP packet that says destination unreachable. I get this on both sides of the TW server. Appears to come from the TW server it self and not a switch or router. I'd like to turn ICMP redirets off. Any clues?
