we have two different subnets, machines talking on oneway only, not both ways

Hello,

I have small issue, I have one ADSL Router (uplink adsl, regular LAN
ports for regular linux machines to access internet), this router uses
192.168.1 subnet, I have some Linux machines in that subnet
(192.168.1.xx), also I have one more Router connected to the one of the
LAN port of that ADSL router, that second router's WAN port was
assigned a static IP address 192.168.1.128, there are some more Linux
machines in second router, its subnet is 192.168.2.xx, I can ping or
ssh or telnet or ftp from 192.168.2.xx to 192.168.1.xx (also 192.168.2
subnet machines gets Internet also), but not the other way, I cannot
reach anything from 192.168.1.xx to 192.168.2.xx, Is there anyway I can
reach the machines in 192.168.2.xx subnet (ftp, ssh or telnet).

if you think, why I am using Two Routers, I need the second router
since I have lot of filters to block most of the websites (useful for
kids, so that lot of sites can be blocked), but this second ADSL
router, I got it recently through my ISP, so that is why I need to use
two routers.

also earlier I was using portforwarding to access machines from
outside, I added portforwarding in ADSL router, that is how I used to
reach all the machines in 192.168.1.xx subnet. now I need to port
forward to 192.168.2.xx machine (one of the machine atleast, from there
I can reach all other machines), How can I reach 192.168.2.xx machines
using portforwarding, any clue.
Thanks in advance, can some exprt drop me a line.

Small extension to earlier message, I can do network opeartion form
192.168.2 subnet to 192.168.1 subnet, but not vice versa, can somebody
give me a clue what I am suppose to do to communicate on both ways.

It sounds like the second router (between 192.168.1.0/24 &
192.168.2.0/24) is doing NAT for the boxes on the 192.168.2.0/24
network.

You can probably setup port forwarding on the second router to allow
access to one of the boxes on 192.168.2.0/24, but probably not more than
one, unless you can turn off the NAT and just do normal routing.

At that point you will need to add a route to the 192.168.2.0/24
network, pointing at the 2nd router, to either the main router, or all
the boxes on the 192.168.1.0/24 network.

Do I have add route on 192.168.1 subnet machines, then can I reach
192.168.2 subnet?. Thanks.

Also, in 192.168.2 subnet, some machines try to mount 192.168.1 subnet
partition, while booting, the machine 192.168.2 subnet tries to mount
192.168.1 partition, it is not booting, it hangs while mounting NFS.

Is there any solution for my problem, or do I need to more explanation
about my problem here?. Thanks.
