Routing Problem :/

RouterOS General

Hello…

I have a network setup as follows:

              Local Office                                   Remote Office


             10.0.0.1/24                              192.168.10.10/24
|Server|<----->ether1|OFFICE|                  |REMOTE|ether1 -------------> (Internet via pppoe dial up)
10.0.0.10/24           WLAN1   <---- WDS ---->   WLAN1
                      192.168.0.1/24         192.168.0.2/24
                          |                       |
                          |                       |
                      Clients                  Clients
                  (DHCP pool 192.168.0.21 - 192.168.0.30)

Router OFFICE WLAN1 (192.168.0.1) and REMOTE WLAN1 (192.168.0.2) are linked via WDS

Router REMOTE ether1 (192.168.10.10) dials up to the internet via PPPoE

Wireless Clients connecting to OFFICE WLAN1 or REMOTE WLAN1 obtain IP address via a dhcp server on REMOTE
Pool - 192.168.0.21 - 192.168.0.30, Default gateway 192.168.0.2, netmask 255.255.255.0

Server setup - IP 10.0.0.10/24 - Default gateway 10.0.0.1

All clients are able to ping anything on the 192.168.10.10/24 network
All clients are able to access the internet
Server is able to ping Routers OFFICE and REMOTE

All clients are able to ping OFFICE Ether1 (10.0.0.1), but are not able to access the server on the 10.0.0.0/24 network.
No router or client is able to access Server on the 10.0.0.0/24 network.

I have the following routes set up:

[admin@OFFICE] ip route> print
Flags: X - disabled, I - invalid, D - dynamic, J - rejected,
C - connect, S - static, r - rip, o - ospf, b - bgp

DST-ADDRESS G GATEWAY DISTANCE INTERFACE

0 S 0.0.0.0/0 r 192.168.0.2 1 bridge1
1 DC 192.168.25.0/24 r 0.0.0.0 0 bridge1
2 DC 192.168.0.0/24 r 0.0.0.0 0 bridge1
3 DC 10.0.0.0/24 r 0.0.0.0 0 ether1




[admin@REMOTE] ip route> print
Flags: X - disabled, I - invalid, D - dynamic, J - rejected,
C - connect, S - static, r - rip, o - ospf, b - bgp

DST-ADDRESS G GATEWAY DISTANCE INTERFACE

0 S 10.0.0.0/24 r 192.168.0.1 1 bridge1
1 DS 0.0.0.0/0 r 41.241.192.1 1 PPPoE OUT
2 DC 192.168.10.0/24 r 0.0.0.0 0 bridge1
3 DC 192.168.0.0/24 r 0.0.0.0 0 bridge1
4 DC 41.241.192.1/32 r 0.0.0.0 0 PPPoE OUT


What do I need to add / change to let clients be able to access the Server on the 10.0.0.0/24 network

Thanks

JuZz,

Make sure you turn on Proxy-ARP on the interfaces facing those priv networks.

JuZz -
What struck me is that you have no default route - if you put one in you should not need to use proxy-arp to overcome your issue… A default route tells the router to route a data packet with an unknown destination path to the router specificed in the default route. The default rule tells the router to lookup any packet with an unknown destination and see what table to lookup to know where to send that packet to…

You’ll also need a a default route rule - they should look like below - ignore the IP addresses and labels - they are ones I use in my network.

[xxxx@RapidWiFiMain] ip route> print

DST-ADDRESS PREF-SRC G GATEWAY DIS INTERFACE

21 A S 0.0.0.0/0 r 192.168.1.1 Public


[xxxx@RapidWiFiMain] ip route rule> print
Flags: X - disabled, I - inactive
0 src-address=0.0.0.0/0 dst-address=0.0.0.0/0 action=lookup table=main
