Can't see an XP box when using VPN

I have a network with a range of 10.3.86.1-254. I have a DHCP server dishing out addresses from 10.3.86.1-99. I have a T-1 line connected. I can VPN into the network, ping, & connect to all the devices. I then connect another internet source (Cable modem) to a router & add it to the network. I then take one of the network clients & static IP it with 10.3.56.103 & point the default gateway to the router connected to the cable modem. Within the network I can ping & RDP the client. When I VPN into the network (coming in from the T-1), I cannot see the client on the network - can't ping by name or IP & cannot RDP. I can, however, RDP into another client on the network then RPD & ping the client with the static IP. What could be causing the client with the static IP from being seen when VPNed in?

I gather the IP you posted was a typo should be 10.3.86.103.
Does the router you use support multiple WAN?

Internet1 -> Router A -> LAN
Cable -> router B -> LAN
Is this your setup?  In this Case even through you use the same LAN IPs 10.3.86.x/24 they are not the same for the purposes of the VPN.  The VPN connection to router A lets the traffic hit the 10.3.86.103 system, but the response from this system is directed to the Cable modem connection where the VPN Connection does not exist. Setting up a route between Router B and router a for the VPN IPs i.e. VPn Ip is 192.168.0.x so you would have router B setup that if it sees a packet destined to 192.168.0.x it should forward it to router A.


You may need to have a setup:
Internet1 -> Router A -> LAN
Cable -> router B -> Router A

Where the port on which router B connects to router A is setup as a load balanced.

Yes it was a typo. I had a feeling it had to do with the route on the router to the cable.
So what you're saying is that the 10.3.86.103 is actually getting my requests but the response is getting routed through the router for the cable therefore never getting to me?

Thanks,

yes.
if you want to load balance outgoing traffic between two providers while using one provider for incoming (vpn, web, etc.), the two external connections must terminate on the same router that srves the LAN
