UDP packets problem

RouterOS General
1

Well,this is my box..


ether1 192.168.1.9
wlan1 10.201.4.1
wlan2 10.201.204.1


ruouting:

Destinaition Gateway pref.source interface


S 0.0.0.0/0 192.168.1.7 10.201.204.1 wlan2
AS 0.0.0.0/0 192.168.1.7 10.201.4.1 wlan2
DAC 10.201.4.0/24 10.201.4.1 ether1
DAC 10.201.204.0/24 10.201.204.1 wlan1
DAC 192.168.1.0/24 192.168.1.9 wlan2

icmp pings works but udp don’t!
all the tcp packets go throu and some UDP(like 53) ,but other UDP(ex. Network assistant 50139) don’t go throu.
Don’t have any firewall rules only nat masquerading(default settings).

only UDP 16. and 17. go throu.


any help?

Forgot to mention that all devices have internet working…

Do i have to configure those ports(that don’t go throu) in a firewall?
any ex.?

I beg to differ. There you can clearly see that the packet went through from 192.168.168.1.107 to 10.201.4.255 (which is a broadcast btw?) to port 50138

If these packets are supposed to see things by using Broadcasts (which is what the traffic shows me), then it’s never going to work - that’s why we use subnetting. A broadcast on one network, will NEVER be visable on another network…

Either way, MT is doing it’s job just fine here…

so you sugest one network with different subnets?
could i set it up like this?

10.201.201.1/201.201.201.1 wlan1
10.201.201.1/201.201.201.2 wlan2
10.201.201.1/201.201.201.3 ether1 ?
