Hello all,

I've recently configured and IPsec VPN between my OpenSUSE 10.2 router
firewall running shorewall 3.4.4 and a friends Draytek Vigro 2930 ADSL
modem/router/firewall.  All is good other than my router can't ping
anything on my friends LAN, however machines on my LAN behind the
firewall can ping machines on my friends firewall without problem.

I've updated my policy file to be as follows:

###############################################################################
#SOURCE         DEST            POLICY          LOG             LIMIT:BURST
#                                               LEVEL
loc             net             ACCEPT
loc             $FW             ACCEPT          $LOG
loc             vpn             ACCEPT

loc             all             REJECT          $LOG
$FW             net             ACCEPT
$FW             loc             ACCEPT          $LOG

$FW             vpn             ACCEPT
$FW             all             REJECT          $LOG
vpn             loc             ACCEPT

vpn             $FW             ACCEPT
net             $FW             DROP            $LOG

# THE FOLLOWING POLICY MUST BE LAST
net             loc             DROP            $LOG

net          vpn         DROP
net             all             DROP            $LOG
all             all             REJECT          $LOG
#LAST LINE -- DO NOT REMOVE


So, I've allowed traffic from $FW to vpn and from vpn to $FW.  Having
looked at the documentation at www.shorewall.net that seems to be all I
need to do.  I can't help thinking I must have missed something really
obvious but if I have I can't spot it.  I've not updated any rules to
allow specific types of traffic to/from the router.  I understood that
the policy should allow everything to/from the router to the vpn zone.
Is that correct?

Kind regards,

Steve.
