we are using a SonicWall box with the default GroupVPN setup and the
internal DHCP is used to configure VPN clients addresses. We are not
using L2TP, just the internal DHCP that comes with the SonicWall.
I've managed to configure OpenSwan to connect and access the VPN
networks, but i cannot get the dhcp part to work.
The problem i have is that when I access VPN resources, my source ip is
unchanged (same as in my LAN) and I would like to be seen as a "VPN DHCP
Client" on the other side.
Here is the config i'm using now :
I've tried to add "rightmodecfgserver=yes" and "leftmodecfgclient=yes"
but with no success. Changing modecfgpull from yes to no have no effect
on the actual configuration.
I've also tried to set "leftsubnet=172.16.0.101/32" but despite being
able to connect without apparent errors (SonicWall logs agrees) packets
are not routed correctly.
Also tried to add leftnexthop and leftsourceip with various combinations
but still no luck.
Maybe after all what I'm trying to do is not supported, the docs I've
found on the SonicWall(ehm...Dell) web site are suggesting this kind of
Does anyone know if it's possible to make OpenSwan get the network
configuration from a SonicWall VPN? What would be a correct
configuration for that case?
Thanks in advance,
