This will change the GUI interface available for OpenSWAN. Which
doesn't work properly in Fedora anyway so I have to do everything
via command line.<br>
<br>
<br>
The sonicwall windows client uses IPSec Tunnel with xauth
authentication. The client config file that you export from the
Sonicwall appliance includes the PSK and other parameters. You
can use openswan to configure an equivalent type of connection,
but you do need to know the PSK, encryption settings, and group
name. Unlike the windows client, a virtual NIC is not used, so
you may also have to tweek some routing/forwarding options on the
linux machines.<br>
<br>
The alternate approach used by the sonicwall is an
L2TP-tunnel-over-IPSec-transport, if enabled on the sonicwall.
The GUI may work better with this- but I think it is also using
openswan or libreswan in the background. This will provide a
virtual NIC on the client. This is same approach used by the
IPSec VPN client support native in MS windows. <br>
<br>
<br>
A few tech savvy people at my work use Openswan for the VPN
client. But it turns out to be such a PITA that we found
for some people it was simpler to purchase a Sonicwall TZ105 for
some remote users, and just configure a site-to-site link.<br>
