EIOP Routing problem [SOLVED]

RouterOS General
1

I have set up an EOIP connect between a MT493 and a MT450 board. I have the tunnel established and am able to ping the routers from the remote locations. However, I am not able to see beyond the routers to any other devices on the network. I have read everything I can find and can not seem to pin point the problem. Any help would be greatly appreciated. My setup is as follows

I am able to ping the 192.168.3.2 address from the 192.168.3.1 router.

EOIP Server Ether1 is a fixed static IP, all other ether’s, wireless and the EOIP are bridged together on 192.168.3.1. The EOIP address is 192.168.4.1

Routes

AS Dest.=0.0.0.0/0 Gateway=66.216.xxx.xxx Gateway Int.=pppoe-user(this is my at&t modem connection static ip) interface=,ppoe-user Distance=1

DS Dest.=0.0.0.0/0 Gateway=68.216.200.148 Interface=pppoe-user Distance=1

DAC Dest.= 68.216.XXX.XXX Interface=pppoe-user Distance=0 Pref. Source = 74.180.xxx.xxx

DAC Dest.= 192.168.3.0/24 Interface = bridge1 Distance=0 Pref. Source = 192.168.3.2

DAC Dest.=192.168.4.2, Interface = from_remote (PPPTP Server) Distance=0 Pref. Source = 192.168.4.1



EOIP Client Ether1 is a fixed static IP, all other ethers and the EOIP are bridged together on 192.168.3.2. The EOIP address is 192.168.4.2


Routes

AS Dest.=0.0.0.0/0 Gateway= 66.208.xxx.xxx Distance = 1 interface= ether1

DAC Dest. =66.208.XXX.XXX Inteface = ether1 Distance=0 Pref. Source = 66.205.xxx.xxx

DAC Dest. =192.168.3.0/24 Interface=bridge1 Distance=0 Pref. Source = 192.168.3.1

DAC Dest. =192.168.4.1 Interface=pptp(PPTP Client) Distance=0 Pre. Source = 192.168.4.2

you have 2 possibilities - either NAT or make proper routing table.

if it is expanded local area network, with tunnel to other location, you have to set routes on all the routers there are, or as a result you wont be able to access resources further than dynamic local route will bring you.

please look up tutorials about basic TCP/IP networking and how it works as you are lacking basic knowledge about basic things you should have known. Good place to start is RouterOS manual with links to knowledge needed.

Thanks for your response.

I do have a basic knowledge of IP systems and routing. I am have never used an EOIP tunnel before and am obviously missing something here.

A little help beyond “read the manual” would be greatly appreciated.

ok, when this is sorted,
think of EoiP tunnel as simple interface, that just sends packets. as name inticates - Ethernet over IP - it is like ethernet interface, if you do not set up ip address, only mac lvl “things” will happen there, if you bridge it - all mac traffic will be able to enter that interface.

so, if you set ip addresses on each end of EioP tunnel, then apply simple routing rules.

EG.

AS - autonomous system
you have two AS, that you want to connect to each other using EoiP tunnel. in one AS you have 4 networks, lets say A 192.168.1 - 4.0/24 on the other one you have B 192.168.10 - 14.0/24

now when you set up EoiP tunnel with addresses 192.168.100.1/24 on A side and 192.168.100.2/24 on B side, then on A side you set that 4 B AS networks should be reachable through 192.168.100.1 address, and you have to make this address reachable (have to route it) from all AS A routers and vice versa for AS B

Thanks again for your help.

I have checked all the routing and everything looks correct to me.

I am able to ping the routers from both sides using the EOIP tunnel, I am just getting stopped at the router.

Can someone explain to me the difference between a ping and a ARP Ping?

If I ping the address of the computer using an ARP Ping I get a response. If I use the normal ping, the ping times out.

I solved the problem, turns out to be mostly firewall issues on the pc’s. Router was doing its job.
