The MTU is 1492 (german Telekom DSL). My firewall uses as last output rule
"ipchains -A output -l -j DENY", this logs the pakets from gnunetd on
port 65535. Even if i insert a rule before this fallbackrule, eg.
"ipchains -A output -i ppp0 -p udp -s $localip 65535 -d  0/0 65535 -j ACCEPT"
the kernel denies theese pakets.

"echo 1 > /proc/sys/net/ipv4/ip_always_defrag" doesn't help.
