eoip/ipip tunnel with routing across it ??

RouterOS General
1

ok i have 2 mikrotiks setup at remote officeswith eoip setup and running fantastically..

but what i would like to know is can i route a block of address’s over that eoip tunnel…

the MT at the main office has the block routed (static) to it and it then routes the block across the eoip link and i can ping the interface that has the address on the remote end, but if i try and trace to it from the main office network it just dies at the mikrotik in the main office all thought if loged right into it, i can get to it.

have buggerd somthing i should not of or is this how it should be and i need to find a different way of configuring this…

thanks in advance

Yes, you should be able to route through an EoIP tunnel.. It’s a virtual ethernet interface basically.. so just make sure your routing tables are setup correctly.

i thought i should be able to do it also, but no go…

in my main cisco gateway i have a route for the network block pointing to the mikrotik.

from the mikrotik there i have the block routed over to the remote side, and it is routed to the address of the tunnel.

and on the remote mikrotik i habe the inerface setup with the address on it..

from the main mikrotik in the office i can ping the other side of the tunnel and the address on the interface i setup, but from the gateway even though the tunnel is setup i can only get to the address of the tunnel on that end, but i can not even ping the address of the remote tunnel end..

this is what have me confused…

i can not figure it out at all

I’m assuming you’re using static routes.. have you defined the routes on the remote end so they can get back to the source?

Can you print the routing tables on both ends of the tunnel omitting the last octet of IP addresses?

Also what gateway is the client using?

on the office MT the tunnel is 200.xxx.xxx.253/30 on the other side it is 200.xxx.xxx.254/30.

the interface i have added is 200.xxx.xxx.129/29

from the office MT i can ping both 254 and 129 and anything behind it.

but from the remote site i can not ping past the office mt and at the office i can ping the MT and the first part of the tunnel the 253 address but not past it

everything is statically routed, i have a nother ipip tunnel running on a nother network with 2 ciscos and i dont have this problem at all…

i know i have left somthing out that is silly but i just can find it,

also here is the routing tables

Gateway router (cisco)

ip route 200.xxx.xxx.128 255.255.255.192 200.xxx.xxx.88
ip route 200.xxx.xxx.252 255.255.255.252 200.xxx.xxx.88
