I need to connect two seperate companies networks together(different IP addressing). They are both trusted and want to exchange information using TCP/IP. I don't want to set up a VPN. What equipment and how would you recommend doing this?

Guess if you don't want to use the internet and a vpn between sites you only having the following choice. That only leaves you with routers at each end and chosing between Frame Relay T1 or a Point to Point T1. Contact your phone vendor and request quotes for this connection. Make sure you understand the difference between FR and PtP. If doing frame the CIR is the real number not the port speed. Important to remember that or you could end up with a T1 at modem 56K speed [full port speed T1 is 1.54mbps but CIR [committed information rate] is your TRUE bandwidth speed with FR. If they tell you that you can "burst" to port speed... they lie] Give a person a fish, they eat for a day. Suggest they internet search and they learn a skill for a lifetime.

I didn't mention that these networks will be directly connected and won't need a WAN connection.

No you didn't :-) Install a router between the two. I would recommend a Cisco for this. Give a person a fish, they eat for a day. Suggest they internet search and they learn a skill for a lifetime.

Another option, if reasonably close, you could put in a gigabit layer3 switch. It can do routing and vlans which will give you more granularity of control. Lot more expensive than a router but long term you will be able to transfer more data faster than if you just tie the two together with a router. All depends on the business plan. Give a person a fish you feed them for a day. Ask a person to internet search and they learn a skill for a lifetime.

You won't get line speed out of an inexpensive router between networks. Especially if you decide to put some kind filtering (when you catch your first virus from them or vica versa). Price a Cisco 3560 L3 switch. If there are mulitple subnets and you need a routing protocol then you can either use OSPF (an open standard) or if you both settle on Cisco equipment then use EIGRP as the routing protocol. You will need to buy the enhanced switch image to support a routing protocol. The standard image allows static routes which may be fine. Micah S. Cox
