This is my situation: I want to connect to my home computer via RealVNC from my office. The pc (192.x.x.30) is connected to 2 routers. Router #1 is my adsl setup(192.x.x.10) Router #2 is a 3g modem router(192.x.x.20). My adsl has very slowww connection(1mb). All devices are on the same network but the default gateway for the PC is 192.x.x.10(router #1-adsl). Can I contact my pc with RealVNC via the 3g modem router(obviously faster) if the computer is on the same LAN? If I port forward the VNC connection to my pc will router#2 be able to find the pc and route the connection if the pc has router #1 as default gateway and dns server? I hope this makes sense.
 
On the 3g modem, do a nat to the inside interface for your source traffic from the internet
The PC will return the traffic to the 3g modem, which will then send it back to you

Sorry you lost me, please explain your solution?
 
But the constant nagging about licenses and change in id? Does it come with an app?
 
How does teamviewer dictate that the traffic will use the 3G router instead of the normal default gateway when connecting?
Unless you statically route teamviewer ranges to the 3G router.

Unless i completely misunderstand the requirement.
But what i thought is he has a PC. default gateway to the normal router.
They have 3G router they want to use for remote connectivity.

Im not sure how teamviewer will know to use the 3G router unless you specifically route the teamviewer ranges to that link.

My idea allows you to use whatever, teamviewer /VNC / RDP etc. Because the source nat will take care of the routing for you

Routing makes no difference, you install TV on the desktop you want to access and the one you are accessing it from, the rest happens seamlessly

Again, he said he has 2 LINES. he uses the default gateway for normal traffic.
he wants to use the other line for remote access.
How exactly does teamviewer know to use the line that the PC doesnt route to.

Routing here, makes a difference, because of his requirement
 
I need the connection to go through the 3g router instead of the adsl router.

yes, which is why i suggested what i did.

If you use teamviewer, you might have to route all team viewer ranges to the 3g device (i am not sure if these ranges are all known)

Otherwise, use RDP. On the 3g router, make a rule that nats traffic from the internet to the inside interface IP (the 192.x.x.x)
use a port forward for the 3389 traffic or vnc traffic and you should be done.

Yes you can, but 2 things would be important.
1) arrange Unrestricted access on your simcard
2) you need to specify 2 gateways on the pc, and then use Metric value and other IP routing to make your chosen program working.

Just to say use TeamViewer wouldn't help, as it will use 1ste gateway to establish connection.

I would rather change my router setup to be the only gateway on the network, and change the router config to-do the routing via 2 WAN's (tell it port so and so must route through WAN 2 - 3G and all the rest to WAN 1 - DSL
 
The 3g connection is linked to my alarm IP card. Why wont the laptop respond to a request(vnc) sent from the 3g router? The router is just another device on the network. The laptop did not initiate the connection the router did.
