|
Hi,
I have a linksys WAG300N ADSL wireless gateway. I have problems with this router using Cisco VPN client 4.6.03.0021. I can establish the vpn connection ok, but they I can't telent to anything through the vpn tunnel or browse using http to the servers on the other side.
VPN passthrough is enabled, (IPSec PPTP L2TP).
For another application I use the Nortel Continvity VPN client through this router no problem at all.
I have another router ( a Belkin 7630) and it works happily with both the cisco and the nortel vpn clients).
Using the Cisco client and WAG300N I do connect on to the Cisco PIX VPN concentrator at the far end and get allocated an ip address in the correct subnet but can't establish a connection to anything else on that network.
Its got to be my linksys config but don't know where to look.
Thanks in advance. |

network and ACLs would be helpful. General VPN and any firewall config would also be useful. A route table would also be very useful.

Hi thanks for the reply.
I use static IP addressing at home.
Both the Linksys (the problem) and the Belkin (the one that works) are set to be 192.168.2.1. (255.255.255.0). Only 1 is powered up ant any one time.
The PC the Cisco client runs on is 192.168.2.79.
When connected with the cisco client (which shows up as LAN 3 on my PC windows 2000 SP4 machine) I get allocated.
Windows 2000 IP Configuration
Ethernet adapter Local Area Connection 3:
Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 172.26.3.130
Subnet Mask . . . . . . . . . . . : 255.255.255.192
Default Gateway . . . . . . . . . : 172.26.3.130
Ethernet adapter Local Area Connection 2:
Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.2.79
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . :
Ethernet adapter Local Area Connection:
Media State . . . . . . . . . . . : Cable Disconnected
LAN 2 is my belkin wireless card. The other is an ethernet NIC I don't use.
I get allocate dthe same IP wither using Linksys or Belkin.
I'm trying to telnet to 172.26.1.77 or run http using IE 6 to that address at the far end of the VPN.
No firewalls turned on at either the home router or the PC the client runs ons.
Route table on client PC with either Linksys or Belkin in place is.

Persistent Routes:
None
I don't have access to the Cisco PIX at the far end of the VPN to check an ACLs but can't see that is an issue if the Belkin works and the Linksys doesn't and all other config stays the same or am I missing something.

seen this before.
Hook up with a wired connection and it will probably work.
need to update the firmware on the router... there is some wacky issue with cisco's firewall and linksys's firmware.
at work this problem started when we updated the drivers on the laptop's wireless card...
you may also want to try changing the transport on the cisco vpn from TCP to UDP (a little more stable over wireless networks it seems) |
