Hi list.

I'm trying to modify our current shorewall configuration (based on 3.2.6) to
support an additional ISP *without* balancing and I have problems with the
VPN.

Here is the old, working, setup

Eth1:  LAN interface. Has 3 IPs (192.168.77.253/24, 192.168.78.254/24,
192.168.80.253/24).
Eth2: WAN interface. 

On the same firewall I run pptpd for external users to access LAN
192.168.77.0/24. The pptpd server assigns addresses in the 192.168.77.0/24
network.

What I'm trying to do is adding a second "ISP" on eth0:
Eth0: 10.17.48.2/23
The rule for routing is that shorewall should use eth0 *only* for traffic to
10.0.0.0/8. All the other traffic should go thru eth2.
I followed the directions for multiISP here
http://www.shorewall.net/MultiISP.html and  tried to disable balance with
this http://www.shorewall.net/FAQ.htm#faq58
The result is that the traffic from LAN is correctly routed to eth0 or eth2.
However the VPN is not working anymore: I can connect to the VPN server, but
I cannot ping any host in LAN 192.168.77.0/24 properly.
I've attached the output of shorewall dump.

I'm trying to ping 192.168.77.250 from 32.174.168.137 and don't see echo
reply.
If I sniff eth1, I see the echo replies from 192.168.77.250. If I look at
ppp0, I only see the echo requests.

Thanks in advance
GV
