[vpn-help] Shrewsoft vpn client with LinksysRv042 - cannot ping, rdp etc

[Srinivasan Subramanian]

I finally figured it out.  The RV042 firewall was enabled and we had 
specified access rules to allow traffic from LAN to the outside.  Given that 
the IPSec was on a new subnet, I had to add rules to allow access and it all 
worked.

Thanks to all for the help

Cheers
Srini

Hi Srini,

I would try to run wireshark on one of the PC's your attempting to send
traffic to via the VPN connection. This will allow you to determine if
the traffic is reaching the target host in question. If the packets are
reaching the host, you should see reply packets. For example, if you are
sending an ICMP request ( ping ), you should see an ICMP reply as well.
If you don't see a reply packet, then its possible that your target host
doesn't know how to route the return packet back to the sender, or it
may have a firewall enabled that is blocking the traffic.

Hope this helps,
