This is on even the Netgear support people can't solve. I Cannot map network drives or use intranet or remote desktop for resources behind my company''s firewall using Cisco VPN Client 4.6.04.0043 and a netgear WGR614v6 wireless router - it just sits there and hangs forever when clicking on a mapped network drive or accessing intranet using MSIE. VPN connection works if I bypass the router and connect directly to DSL modem.

Here is what I''ve already tried:

Turned off firewall on my Dell laptop (running Windows XP SP2)

Here''s what I''ve tried so far on my router and nothing has worked:

Used port forwarding for UDP ports 50, 51, 500, 4001 and 1723 for my laptops IP
Disabled the SPI firewall
Checked "respond to ping on internet port"
Upgraded firmware to V1.0.11_1.0.7NA
Disabled Access control
Disabled all security (normally WPA-psk)
Set MTU to 1300 on both Cicso VPN client and WGR615
set MTU to 1430 on both Cisco VPN client adn WGR615
Added laptop's IP to DMZ server
Tried both IPSec over UDP and IPSec over TCP on Cisco VPN Client
Reset router to factory defaults

Still no go on VPN. Can someone suggest something else for this router other than what we already know which is this VPN client and router combination are incompatable? Perhaps a setting in the laptops Intel® PRO/Wireless 2200 that I can tweak? One post I read said the user tried a Cisco Systems Aironet PCI Wireless LAN Adapter and got it to work but that would be my last option and not guaranteed in my setup.

Thanks

It might be that your not getting a remote IP address when you connect...that would account for why your intranet and map driving are failing.

Are you getting a valid IP address? I.e. after establishing VPN connection when you do Ipconfig /all what does the IP address for the PPP WAN connection show? - is it valid IP address for your companies network? If it's 169.x.y.z that's where the source of the problem

I just did an IPconfig and I'm getting a valid DHCP address from my local router and a valid static IP behind my company's firewall on my Cisco VPN adapter. I just tried reserving an IP under the router's LAN IP setup settings and even that didn't work.....

Got $W&$*%^ Cisco...forgive me for my outburst but this is what I hate about Cisco...even though they are supposed to be compliant with IPSEC they are always putting in proprietary stuff to keep the world enslaved to the "Cisco" way...Can't stand them.

There are rumors that to get Cisco VPN clients to work with XP SP2 you do have to open up some additional ports.

UDP Port 10000 (or any other port being used for IPSec/UDP)
NAT-T (standards-based NAT Transparency) port 4500, and verify that
TCP port configured for IPSec/TCP is correct and open.

These are at least 2 more ports listed than you have in your post, and VPN is so finiky that any one wrong port blocked causes the connection to fail.

My advise if that doesn't work...does your company demand you use Cisco VPN client? If not Try another manufacture who is truly IPSec compliant and no priopietary ports to complete the connection...if it works...pitch that Cisco VPN client disk as far as you can throw it!

Just ran into a similiar problem with a Netgear router, Intel 2200 wireless and Nortel Contivity.

VPN would never connect. Turns out when testing doing extended Ping to the router and an address on the web, the wireless link drops for about 10 seconds when the VPN trys to connect.

Took a 2nd laptop with a different wireless card and performed the same Ping while trying to connect to the VPN. Then machine with the VPN client and the Intel 2200 dropped, however, there were no drops with the other laptop.

I really do not think the problem is with the Netgear router, I think the problem is the Intel 2200. The driver for these Intel 2200 are a real POS! I may try a PCMCIA card in the machine with the VPN client to bypass the problem to see if it is the Intel 2200, which I think is the problem.
