wan connectivity over internet

We are in the process of moving our offices to our new premises. To enable smooth shifting i am trying to establish a WAN connectivity between these two offices that will enable me to do the shifting gradually.

What I have:

* 256K leased line on both sides with static IP#s
* 2MB DSL connection at the new site with dynamic IP
* Cisco VPN Router - 1 # (I can get one more of this if required)
* Cisco Concentrator - 1 #

Currently I am using the VPN router and the concentrator with citrix server. However this requires installation of ICA client. I would like to establish a WAN between 2 offices and setup a DHCP server in the new office. This way, the users can directly go and plug their equipments in the new premises and log in to my domain - this is the key.

I will give bonus points to anyone who gives me a solution with ways to implement it - THIS IS URGENT. I am also trying to hire a local expert (Dubai) to do this job for us. Any hyperlink that will give instructions would also be helpful.

It is unclear exactly what problem you are trying to solve.  It seems that you are already doing VPN.

If you set up a VPN tunnel between your remote site (Cisco router with IPSEC) and a Cisco VPN concentrator, your networks will be connected and appear as a "routed" internetwork.  AT the remote site you can have a DHCP server servicing the local machines.   Citrix clients shouldn't have any diffiult connecting to the main Citrix server at the central site.

The IPSEC security policies on your router can be "tuned" to allow/disallow protocols/ports as your security policy dictates.

I am currently doing this with a Citrix farm at the central site and multiple remote VPN tuinnel connections with varying security policies.  Some are wide open and others are restricted to just Citrix protocols (tcp 1494 and udp 1604).  Tunnels stay up indefinitely.

Does this answer your question or am I missing something?

I have actually called a network engineer who has tested something in my office and i am going to try out this on Saturday. I believe he has used IPSEC...and if it works on saturday you will get it anyway for trying to help me.. Otherwise, i will revert with more questions ;o)

Not a bad idea to bring someone in to help out. Configuring sdsl with authentication an IPSEC VPN tunnels isn't exactly a beginner task.  Good luck in getting your linl up and running.

sorry friend. After this I had to travel and hence couldn't update. The guy managed to establish the VPN though the speed was painfully slow - You get it for your efforts.

thanks again
