router connectivity
 

i got 2 routers, one is on 192 and the other one is 10. there seems to be a problem when i am accessing 10 network from 192 although, when i do the opposite it works correctly.
router configured with 192 is Huawei 510
router configured with 10 is Dlink - DIR 618

i have even tried to open 2nd interface on Huawei 510 even then it doesnt seem to work.

Hi Syed,

What exactly the problem is when you say there is a problem?

Also paste the routing table from both the routers. Also the neighbour list from both the routers and their interface configuration.

the problem is connectivity itself, i am unable to access the router page of router B which is on 10's network from Router A which is on 192.

Router A - routing table.

> route

Usage: route add <IP address> <subnet mask> <[<gateway>] [<interface>]>
route delete <IP address> <subnet mask>
route show
route --help
> route show

Kernel IP routing table

the above router is configured on 192. however the 2nd interface was turned on deliberately so that Router B can have access to router A. -
the interesting thing is the 2nd interface on Router A is br0:0
- i am unable to set gateway on br0:0
lol there is no sysctl.conf for ip_forwarding :P

-- on router B the configuration is set, able to ping 192 as well as 10.

Try this

echo 1 > /proc/sys/net/ipv4/ip_forward

and then try to add a static route on router A on br0:0 interface to router B.

thanks very much able to fix the issue, how ever forwarding packets plays a crucial role,
the next thing i did was by adding a static route in 192.168.1.1 to destination 10.0.0.0 and gateway set to 192.168.1.2[other router which is on 10]
thanks you.
