Hi all.
I configured Shorewall (ver. 4.4.26.1) working with two balanced isp and
everything seems to be ok.
I need also that when one of the isp connection falls down, all outgoing
connections should use the other isp.
I configured the swping script that monitors the two connections and
restarts Shorewall when one link goes down.
The problem is that, when one link goes down, the swping script restart
Shorewall correctly (shorewall -f restart), but the routing table of the
firewaal seems to be unchanged and all connections continue to go through
the wrong provider.
My /etc/shorewall/interfaces file:
net eth0 detect optional
net eth1 detect optional
loc eth2 detect
My /etc/shorewall/providers file:
VO 1 - - eth0 192.168.20.254
balance=3
TI 2 - - eth1 10.0.3.2
balance=1
My relevant /etc/shorewall/shorewall.conf options:
RESTORE_DEFAULT_ROUTE=No
ROUTE_FILTER=No
TRACK_PROVIDERS=Yes
USE_DEFAULT_RT=Yes
May be something is wrong but I cannot see what.
Any suggestions will be appreciated.
Many thanks.
