Hi, this is my problem...

I have two remote Lan's connected with wireless bridge using tree MT routers and double EoIP configuration.



this is the configuration:

MT1:
eth 1 IP: 192.168.0.10
wlan1 IP: 10.0.0.1
EoIP tunnel 1: remote IP: 10.0.0.2 - Tunnel ID: 1
Bridge 1: ports= eth1, EoIP tunnel 1

MT2:
eth 1 IP: 192.168.0.200
wlan 1 IP: 10.0.0.2
wlan 2 IP: 10.1.1.1
EoIP tunnel 1: remote IP: 10.0.0.1 - Tunnel ID:1
EoIP tunnel 2: remote IP: 10.1.1.2 - Tunnel ID:2
Bridge 1: ports= eth1, EoIP 1, EoIP 2

MT3:
eth 1 IP: 192.168.0.11
wlan1 IP: 10.1.1.2
EoIP tunnel 1: remote IP: 10.1.1.1 - Tunnel ID: 2
Bridge 1: ports= eth1, EoIP tunnel 1

The network from Computer 1 and Computer 2 work fine but I have problems with UDP ports.
Some test result using bandwidth test:

TCP from PC 1 to PC 2 OK (both directions) (about 8/10 Mbps)
TCP from PC 2 to PC 1 OK (both directions) (about 8/10 Mbps)
UDP from PC 1 to PC 2 and from PC 2 to PC 1 FAIL (0 bps).

If I repeat test using Btest utility in winbox from MT1 to MT3 all work fine!!!
From MT 1 to PC 2 FAIL!
From MT 3 to PC 1 FAIL!

I'm becoming crazy with this problem! I need to work with UDP 3001 port.

Suggestions?

Thank You

Paolo

Are there firewalls on the pc's?

Eh, no.... All firewall are disabled...

1. try using different MAC addresses on each tunnel.
2. mt2 wlan interfaces in ap-bridge mode grouped in bridge together with ether, then eoip tunnel between 1 and 3.

i have the same problem
try to increase MTU
sry for my english )
