Client set up with multiple NICs and router

daytooner

First problem: I have a server that has two NICs, each on separate subnets. One is for my LAN (xxx.xxx.1.xxx), the other for a dmz (xxx.xxx.0.xxx). The dmz is connected directly to a cable modem router (on the '0' subnet); the LAN is connected to its own router that's then connected to the modem router. The dmz server is set up to route all of its WAN traffic via the dmz NIC.

How do I get to openvpn cloud via the dmz NIC ?

Second problem: I would like to have the vpn on the modem router, which is a TP-Link R600VPN. But I can't figure out how to upload the .opvn file to it (documentation seems to point to other devices :-( ). Anyone know this router?

Any help with these, especially the first problem, greatly appreciated.

TIA

If a router on the network knows that the IP requested is external then However, if you are on a network with other DHCP clients, using Configuring two or more NICs on the same subnet may cause communication problems.

It is becoming commonplace to have more than one Ethernet adapter in a PC or embedded controller, especially in systems where wired and wireless adapters are both present. However, the presence of more than one Network Interface Card (NIC) can cause connectivity problems if each network interface is not carefully configured to account for the overall network layout. This tutorial outlines basic Ethernet networking concepts, explains why incorporating multiple NICs can cause problems, and provides best practices to follow when working with a multi-NIC system. In addition, several common scenarios are explored, including an NI Real-Time Hypervisor system that features a complex network configuration.
