I'm trying to get packets routed over dial-up interface however without any success. I connect to remote device (PPP over modem) and packets are sent to the device and it is reachable. Device has default route set on incoming PPP connection. I'd like to access local ethernet address of computer that dials-out (from remote device to dial-out computer). However, packets are simply not routed - I can verify that packets are received from remote device on DUN interface with Network monitor, however they end there. I have disabled firewall and enabled routing (IPEnableRouter set to 1). OS is windows 7 Professional.
So network looks like this:
192.168.1.1 - ethernet, 10.0.0.1 p-t-p 10.0.0.2 (remote device), default route on p-t-p interface on remote device.
I'd like to access 192.168.1.1 from remote device. Is that possible?
I have set up multiple linux embedded machines connected over p-t-p interfaces (chained 5 of them, 2 p-t-p interfaces on each except first and last with one + ethernet interface on each) - and that happily routes and all interfaces are accessible (moreover RIP sets route automatically). I'm trying to replace legacy *nix system that also routes that. So this would obviously be windows limitation?
Also if you have windows machine with two network cards it will route the packets once IPEnableRouter is set. However not on DUN interfaces.
