Linux dedicated server invisible on LAN

[Topspeed]

i'm running some cs:source dedicated servers on a debian-PC on LAN, but unfortunately they aren't visible in the serverlist. by connecting to the servers via "connect 10.0.0.232:27015" there aren't any problems. server runs perfectly, but aren't shown in the serverlist in LAN-section.
any ideas?
thanks for help!

some configs:
/etc/network/interfaces:
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 10.0.0.232
netmask 255.255.254.0
network 10.0.0.0
broadcast 10.0.1.255
gateway 10.0.0.1
dns-nameserver 10.0.0.2

/etc/resolf.conf:
search
nameserver 10.0.0.2

start-script:
screen -dmS public ./srcds_run -game cstrike -nomaster -insecure +sv_lan 1 +ip 10.0.0.232 -port 27015 -tickrate 66 -maxplayers 24 +map de_dust

I have the same problem when I add the internal IP(-192.168.1.100) for my server. I'm guessing that might be why you can't see it either. Seems to me to be a bug in srcds but I don't have any trouble connecting to mine either(usually). Actually tonight for some reason I can't connect to either of my Linux servers. One of the machines is dual-boot and when I run the XP based server I can get into it. On Linux servers I get an error about not being able to verify my steam ticket. I have connected to other servers on the internet but of course I don't know which are Linux and which are Windows. It would be interesting if it's a Linux problem again.
