Thank you But it doesn't work. Irreco displays 'can not open socket'.

iptables -F INPUT/OUTPUT/FORWARD
iptables -P INPUT/OUTPUT/FORWARD ACCEPT
selinux=0 (I use Fedora)

lirc <-> lirc from one pc to another works, for example:

PC1
lircd -c 192.168.1.119 -H udp -n
PC2
lircd -l -H pinsys -n

wlan basestation might have some kind of filtering / firewall / nat which breaks things
If I start httpd on port 8765, I can access it with N810 and I'm in the same network (192.168.1.0/24)

edit: tcpdump & other informations added

at 1st start or Irreco, I get following tcpdump (Server: *.254, N810: *.40)
[root@server ~]# tcpdump -nni eth1 port 8765
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 96 bytes

After that, Irreco doesn't respond. Now I killed Irreco and it looks like lircd dies too:
[root@server ~]# tcpdump -nni eth1 port 8765
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 96 bytes

00:13:22.881524 IP 192.168.1.254.8765 > 192.168.1.40.55734: R 0:0(0) ack 126136819 win 0
After that, I get the open socket message on N810

Some other informations:
[root@server ~]# rpm -qv lirc
lirc-0.8.1-1.fc6
[root@server ~]# ps ax | grep lircd
25253 ? Ss 0:00 /usr/sbin/lircd -l -H pinsys
