We have a managed Internet connection from a telecom provider which uses a Cisco 2621 and the IOS Firewall (I believe) software as the CPE. I do not have access to the router and have only the basics of the configuration. The management service level is minimal (by contract); I generally need to provide at least the basics of any change I require. Given the overall situation with this service provider I am not even sure they have a customer engineering group any more.
I have an end user who needs to connect to a remote system based on a Linksys WRV54G using the EasyVPN client software. This client connects successfully on an open Internet connection (e.g. at Starbucks), but not surprisingly fails on our network.
Problem is - I can't find anything in the documentation or on the Linksys web site telling me what protocols and ports I need to open to make the connection work. They apparently assume the client can use any without restrictions, which is not the case on any corporate network I know of.
I have submitted questions to Linksys support over the last 6 days and received no response, within 24 hours or otherwise. Of course the unit comes with no support contract.
We ran an Ethereal trace and examined it to the best of our ability, but we don't see anything obviously wrong or any clear indication of how the connection is occuring/failing.
Does anyone have any experience/insight on connecting with this client? My advice to not buy the Linksys was already disregarded.
Thanks.
