Q3 Dedicated - the client does not connect via LAN

Question

linux

Good afternoon!
I have a server with OS:

Linux iceberg 3.4.0-030400-generic #201205210521 SMP Mon May 21 09:22:02 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Unpacked, configured and has its own user:
Q3 1.32b linux-i386 Nov 14 2002
Problem: I'm running a dedicated server. I try to connect to the server from the Linux q3 client from the local network, I get

Waiting Connection... 3..5..10... 70...n.

The server was not found in the list of servers in the LAN section in the multiplayer window either.
I start the server like this:

[email protected]:~/.q3a/baseq3$ /usr/local/games/quake3/q3ded +set sv_punkbuster 0 +set net_ip 10.0.1.5 +set net_port 27960  +exec ./maprotation.cfg

Began to sin on network problems.
The server is bound to a port, visible from the localhost:

[email protected]:~$ sudo netstat -alp --numeric-ports | grep 27960
udp    0     0 10.0.1.5:27960          0.0.0.0:*      9521/q3ded

and visible from other machines:

[email protected] ~$ sudo nmap -sU 10.0.1.5 -p 27960
. . . 
27960/udp open|filtered quake3

Almost default, taken from here .
I ask someone to respond if I experienced similar problems, the English Internet is silent.

Answer 1

27960/udp open|filtered quake3

open|filtered means that it is not possible to determine whether it is open or filtered. What iptables -vL says

Answer 2

Is there a verbose mode in the server logs? Is there something going on there?
