How to make 2 lan works together???

[bohosh]

Hi all,
I have one home server and 2 ISP connections( 2 real-static IP addresses from 2 different ISPs ). I have 2 routers and 2 LAN cards in my PC.
First lan:
IP:192.168.1.10
Mask: 255.255.255.0
gateway: 192.168.1.1
dns: 192.168.1.1

Second lan:
IP:192.168.1.20
Mask: 255.255.255.0
gateway: 192.168.1.2
dns: 192.168.1.2

And my problem is: when one LAN works, the other sleep.
How to make these 2 LAN work together?? I use windows.
Any ideas???

Thanks in advance!!!!

I'd probably want to redesign the entire thing from scratch..first...finding out why you are using this setup in the first place.

Why do you need 2x public IPs?

What hardware do you have?

I have two working places....and from first place I have good speed from first ISP...and from secound working place I have good speed from second ISP...that is the reason that I have 2 public IPs.

Hardware?? PC?? Routers??

Routers, modems, etc....yes.

So...these two networks..are in two physically different buildings...such as across town or something like that?

[bohosh]

Yes....these two networks are absolutely different.
I have Linksys RV042 and TP-Link TL-R460
My first network is PPPoE and It's connect through Linksys.
Second connection is static IP and it's through TL-Link router.
I bought this router (RV042) because It is dual wan...but after many experiments I have the same result....if one wan works..the other sleep.

I my goal was to connect these two networks...I'd utilize the same router on each network...a router that supports "router to router VPN tunnels". Which the Linksys/Cisco RV0 series does support. I use an RV082 at home..to my office..full time tunnel..have quite a few of them at some clients sites also..they work well (well..the 082 and 016 models...I've used a few 042 models but only on edge networks..with not router to router tunnels)

I'm not absolutely sure but your problem maybe your adressing scheme. It looks like you have 2 networks using the same network adress. I think this is why only one seems to work at a time. Try using this address for the for one of them XXX.XXX.2.1 . The third octet usualy represents the network address and the fourth is for the host address.

First lan:
IP:192.168.1.10
Mask: 255.255.255.0
gateway: 192.168.1.1
dns: 192.168.1.1

Second lan:
IP:192.168.2.20
Mask: 255.255.255.0
gateway: 192.168.2.1
dns: 192.168.1.1

The dns IP depends on which lan the dns server resides on, no subnetting should be needed as the 192.168.xxx.xxx is a private addressing range, and I take it your router then connects to a modem or other type of device containing the public IP.
