Hi,
11:51:25.253733 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto UDP (17), length 221) radius-1.restena.lu.tdp-suite > eomund.restena.lu.radius: [udp sum ok] RADIUS, length: 193
Maybe the setsockopt() has to be done after the bind()...
I played around a bit with this. Turned out that no matter where I placed the code in this function, it didn't have any effect. Then I grep'ed the code for other socket() calls and found the only other occurence in main/listen.c: listen_bind() I replicated the code there and now all packets leave the server with the DF bit cleared (works for both replies and self-initiated messages).
