Problem with VPN from ASL 4.009 to 3com Secure GW

Pyro411_01
I'm currently working on an Astaro 4.009 box that has a VPN connection to a 3com Cable/DSL Secure Gateway.  The problem I'm experiencing is anything behind the firewall can not contact anything behind the 3com unless a device behind the 3com starts communication "IE a constant ping to a device behind the ASL Box" The problem being... when a constant ping goes, it'll send about 27 pings then drop 3 & restart the VPN connection.  I'm not sure if I just missed something simple but a bit of the info of my setup is below.

ASL box...
192.168.0.0/255.255.255.0 Endpoint "Ext IP"

3com
192.16.1.0/255.255.255.0 Endpoint "Ext IP on diff ISP"

Setup to use Standard VPN, with 3des & a PSK

on the ASL box... basic Masq is going... Int-Net to Ext-Interface.  I've tried to add routes statically from point to point but that had no effect either way.  The rules have been setup on both ends to allow the proper networks in/out.

Any help would be welcomed & helpful.

Thanks.  [:)]

    Andrew,

    if the remote side is a dynamic assigned address it is clear that Asatro cannot establish the connection itself. Once a tunnel is up it should be up permanently - maybe there is a problem with IKE or rekeying or whatever. If you use PFS, switch it of as first meassure. Check the vpn logs for suspicious entries.
