Hello,
i run into trouble using tinc in switch mode. Its a simple setup with 2 hosts. Both running tincd 1.0.4 (Debian testing) Setup host A: Server, does not make connections to host B. The vpn0 interface is part of a Linux bridge, witch is ipv4 configured. Setup host B: Makes connections to host A, beside this its configured similar. Now it seems large packets can not be transmitted. I verified it step by step the way with tcpdump. A ping with a size larger then 1400 byte gets not reassembled in the tincd on host B, no matter witch side i use. On host A i see the fragmented udp packets arrive, assembled to a large ping and show up on the bridge interface. Then those pings gets answered and find there way back to host B nicely. They arrive on host B as udp fragments but then dont show up in the bridge. So it seems host B disassembles the packets to udp but not reassembles them. At least i can see the pings. By the way, it seems the PMTU setting has no affect. I lowered the MTU size to 1400, but udp fragments still have a size of 1524. Any ideas? Thanks, Axel _______________________________________________ tinc mailing list [email protected] http://brouwer.uvt.nl/cgi-bin/mailman/listinfo/tinc
