Troubles connecting to office VPN with laptop on wireless network?

Hi,

I recently got an acer aspire 3000 with the standard wireless network card that is comes with. I also purchased a linksys wrt54gs wireless router.

I was able to set up the wireless network securely and can connect to the internet with no problems.

However, when trying to connect to the office vpn, I have to renew the dhcp numerous times before it will register me on the office network. It will only go as far as verifying the user name and password, then give me Error 721. I've also noticed that the connection will also drop if I am not active on the network for a short amount of time.

I called linksys support and they directed me to set the port triggering for tcp port 1723 to forwarded range 500. That now allows me to connect with only having to renew the dhcp - prior, I had to recycle the router each time - which was really defeating the purpose of a wireless network!

The wired desktop connects no problem.

ANy suggestions?

My laptop is running WIndows XP sp2 and all updates are installed and up to date. The office is running Win SBS 2003 and the VPN is the included program with that. All updates are also installed and up to date.

Thanks,

Laura

 

Just a quick question, are you trying to connect both the desktop and notebook at the same time? In some cases, since you're behind a router using NAT, you may not have 2 simultaneous VPN connections from the same router.

You may also want to check to make sure your Internet Firewall in XP is disabled or configured correctly to allow VPN access.

Update: Also, you need to make sure the router has VPN Pass-Through support. You can't initiate a VPN connection if the VPN server has IPSEC enabled.

Just wanted to let you know what happened with my problem.

I was speaking with a technician from our technology provider who had come to the office to fix another problem. I asked him if he had any suggestions and he told me it was probably a conflict between the ip address of the router and the vpn address. When I changed the 3rd number of the local ip address on the router settings, all was fixed.

Just wanted to pass the info along just in case someone else like me has such a problem.
