It's happening for IPv4 here as well as IPv6. I have to set my MTU to 1496 bytes on ppp0. The symptom was that calls made to Internode's Nodephone service from my FreeSWITCH installation failed - that is, SIP packets were dropped on the way out. Setting MTU to 1496 was enough to solve it. I just tested again: ip link set mtu 1500 dev ppp0 called a Nodephone test number - no connection. ip link set mtu 1496 dev ppp0 Repeated the call - it worked. When originally diagnosing the problem, I ran pings of different sizes and verified the cause. _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
