2 Networks Intercommunication.

This is how i have my network setup now.

both networks are connected to my main server with 2 network cards.

eht0 is on 192.168.1.X
eth1 is on 192.168.2.X

eth0 is my dsl network, and is the connection box 1 should be using
eth1 is my cable network, and box 1 should be using it to run HALF-LIFE DEDICATED Server only ( unless i add more )

what i want to do is force the HLDS to bind to that access, thats fine i can do that via the config

but my other problem is that i want both networks to be able to talk to each other

so that me on 192.168.1.X can ping a box on the 192.168.2.X network and have access to the routers web interface via my 1.X network

what i need is a way to do this, i tried routing, but i'm not sure what to enter, it makes sence to me but dosen't seem to work.

btw all this is on a network mixed with gentoo and redhat. box 1 is a Redhat 8.0

thanks in advance, Jon

okey so i been playing around, i added routes from the cable router as follow

Destination Lan IP Subnet Mask Default Gateway Hop Count Interface
192.168.1.0 255.255.255.0 0.0.0.0 1 Lan
Destination Lan IP Subnet Mask Default Gateway Hop Count Interface
192.168.2.0 255.255.255.0 0.0.0.0 1 Lan

made some changes to my firewall on the number 1 box
and now that box is able to access the web interface at 192.168.2.1
and able to ping on both networks 192.168.1.X & 2.X

also added the boxes to my hosts and it seems to work out.
+ i added some routing information on the box 1 as i added to the router.

so now if i under stand it properly i just need to add routing information to my other router and it should fix the problem?

can anyone confirm this for me?
thanks

soo...no one knows...

First off, system 1 needs to have the ability to route. Under most linux's edit /etc/sysctl.conf and make sure the following line is uncommented (or added to the file) 'net.ipv4.ip_forward = 1'

The DSL Router must have a static route that points 192.168.2.0/24 to the IP address of system 1 on interface eth0

The Cable Router must have a static route that points 192.168.1.0/24 to the IP address of system 1 on interface eth1

System 1 will have to have the default route pointed to 192.168.2.1 (the cable router). There are other ways to handle this, but they are not easily done..

okey, i re-aranged my setup. and now box 1 is on the dsl router and now im on the cable router (linksys) i want to be able to ping the other network.

how would i go about that.

Need more info.. Another diagram might would help..

okey well no other diagram yet, but i did manage to fix the problem and wanted to post my sucess just in case some one was actualy reading my posts


anyway!

it all started with me playing Ninja Gaiden on my xbox, and then i got to think hey, why not mod the xbox so i can load games faster and maybe overclock it....so i started reading up on it....then when to a irc server to talk to some xbox guys to get there opinion on what i wanted to so with my xbox...then some dude out of nowere was playing and said

[3:02am] <Alienz> ask me anything
[3:02am] <+M|6> anything?
[3:02am] <Alienz> yes, anything
[3:02am] <+M|6> hmm
[3:02am] <+M|6> let me think

then i told him about my dual network problem.....he told me
[3:16am] <Alienz> M|6, try a cross over from one router to the other

and i did, with no luck since my main router is on 192.168.1.1 and my other network is on 192.168.2.1 they would not talk...so i got to thinking hey why not put them on the same internal ip 192.168.1.X and just space them appart

so now i have it setup as:

DSL Router: 192.168.1.1
Computers on that DHCP: 192.168.1.2/3/4/5 and so on
&
Cable Router: 192.168.1.100
Computers on that dhcp: 192.168.1.101/102/103/104 and so fort

and now i'm able to talk to both networks internaly !!!!

+ i got to use my one and only cross over cable i had from another network!
anyone have any questions? don't ask me =p
