2 incomming connections 1 LAN

[cyford]

hi, i have too routers too the same network. it seems coming in the network from the outside i can only reach the computers with that router as the default gateway... how could i make incoming connections work on my secondary connection as well

Outgoing connections work on both routers

i know the default gateway holds arp request.... and handles nat...

but how can i get the second router to route incoming connections to servers which use a different gw than itself?

each router has a difernt isp
the router is setup in router mode, issue happens on a default setup.. only 2 nics

i think RIP needs to be installed on both routers and have arp address translated from both routers... this way router2 can get the arp from router1 too connect to its pc's

if all node connections on local lan, this can be achieved by broadcast....
i think this is why it works local

I think a better network diagram would be helpful, along with the hardware. If I understand you right, you have 2 external (internet) connections and 1 LAN, however you want UT to have only 2 NIC cards? UT does work with multiple WAN connections, however I believe you have to have 3 NIC cards minimum for this to work, as well as the module installed which routes the traffic.

You don't, plane and simple.

If you have two WAN connections, and those WAN connections are handled by a separate router, the clients on the network will only be able to communicate with exterior machines via the default gateway they have defined.

There is a reason the word for that configuration is "Default Gateway", or "Gateway of Last Resort".

It's the gateway that is used when the computer has no clue what to use. Which is always the case with Internet connectivity.

If you want consistent port forwarding capacity across two WAN connections, you must aggregate the connections with a single router that can handle both connections. At that point, each client on the network has a single router to communicate with that can deal with egress and ingress traffic.

Untangle can do this, you need a minimum of three interfaces and the WAN Balanacer module.

Ok so it is possible to do as you want, but it will require you manually updating the routing tables on each and every workstation. And even if you take this insane step, for any given internet IP range you specify, you can only use one router.
