Problem with routing

RouterOS General
1

My situation is this. I have 4 networks. Networks 10.10.3.0/24 and 10.10.4.0/24 are connected to router which IP adress is 10.10.1.0/24. Those routes are connected via direct wireless links. Router 10.10.1.0/24 is also connected via wireless link to router on 10.10.2.0/24 network where I have an Internet connection.

I can ping from 10.10.2.0/24 network to any but I can only go to 10.10.2.0/24 from other routers when I turn on masquerading on 10.10.1.0/24 router. Why? I don’t want/need masquerading on local networks, just on Internet out account… Sorry for my english and I hope you understod me.

Thx

hi pospanko,

i have a simple tip for you. if you want to anybody help you in this forum, you need a bit more recently (and clear, comprehensive) introduce situation and mark accent of the problem.
i personally do not understood nor what “your situation is”, nor what your problem is.
after you redefine your post and make it more clear, there are many people who can help you.
understand my post absolutely frendly. my english is worst actually, so i have similar problems to communicate in this forum, such like you.

best regards,
C. G.

Yes, I am fighting with myself to explain what’s bothering me. I’ll post a simple picture and after that I’ll try to explain my problem.

This are my settings:

Mikrotik 1:
IP adresses:
wireless card for clients - 10.10.1.1/24
link card to MT2 - 100.100.102.1/30
link card to MT3 - 100.100.103.1/30
link crad to MT4 - 100.100.104.1/30

Routes (only static):
10.10.3.0/24 gateway=100.100.103.2
10.10.4.0/24 gateway=100.100.104.2
0.0.0.0 gateway=100.100.102.2

Mikrotik 2:
IP adresses:
wireless card for clients - 10.10.2.1/24
link card to MT1 - 100.100.102.2/30

Routes (only static):
10.10.1.0/24 gateway=100.100.102.1
10.10.3.0/24 gateway=100.100.102.1
10.10.4.0/24 gateway=100.100.102.1
0.0.0.0 gateway=dynamic assigned IP

Mikrotik 3:
IP adresses:
wireless card for clients - 10.10.3.1/24
link card to MT1 - 100.100.103.2/30

Routes (only static):
0.0.0.0 gateway=100.100.103.1

Mikrotik 4:
IP adresses:
wireless card for clients - 10.10.4.1/24
link card to MT1 - 100.100.104.2/30

Routes (only static):
0.0.0.0 gateway=100.100.104.1

I use static routes. This configuration doesn’t work. Why?
I can ping from MT2 to any Mikrotik router.
I can ping from MT1 to any router.
I can’t ping from MT3 and MT4 to MT2. I can only when I turn on the masquerading on MT1.

I really hope that this is more clear presentation of my problem…

Try adding to MT 2


100.100.103.0/30 gw 100.100.102.1

100.100.104.0/30 gw 100.100.102.1
