I have unsuccessfully tried to help my wife connect her Windows XP laptop to her work VPN over our home wi-fi network. I have a WRT54GS v.4 router with the latest firmware, WPA2 encryption. It connects to the VPN just fine but is unable to ping any internal IP addresses and I get the following log message everytime.
1 09:58:43.546 10/10/09 Sev=Warning/2 CVPND/0xE3400013
AddRoute failed to add a route: code 87
2 09:58:43.546 10/10/09 Sev=Warning/2 CM/0xA3100024
Unable to add route. Network: c0a801ff, Netmask: ffffffff, Interface: c0a801ed, Gateway: c0a80101.
I have tried the following troubleshooting tasks:
a) Plugged her laptop directly to the cable modem >> Works like a charm which makes me think it has got to be a router issue.
b) Reset the router to factory defaults, tried running it without any encryption, tried running it in DMZ mode >> No joy, still get the same above error message in the VPN log.
c) Opened up ports 500 and 1723 for TCP/IP and UDP with her laptop's IP address >> Still no luck.
All passthrough options are enabled for VPN in the router's config interface. I have also tried disabling the router's firewall.
I am at my wit's end here guys. Is it possible that the WRT54GS isn't VPN friendly (although it seems very unlikely) and I just have to get another router? Any help is appreciated.
The VPN is configured for IPSec/UDP
