After manually reflushing iptables and restarting Shorewall, I repeated the above test. This time ppp0 appeared in the IP Configuration section of the dump. I've attached that file as well, in case it is more relevant that the previous one.On 2012-03-12 18:08, Tom Eastep wrote:On 3/12/12 4:00 PM, "dtucker"<[email protected]> wrote:After changing the entries in the DUPLICATE and COPY columns of /etc/shorewall/providers to '-' and adding KEEP_RT_TABLES=Yes ROUTE_FILTER=No USE_DEFAULT_RT=Yes I was able to get pings to work out of the ppp0 interface when brought up, and then to continue to work out of the eth2 interface when the ppp0 interface is brought down. However, I am still unable to get pings to work out of BOTH interfaces when they are both up at the same time. Any ideas on how to enable that? Pinging out eth2 when ppp0 is up just hangs (there is no "Destination host unreachable" error like before).For *any* Multi-ISP issue, we need to see the output of 'shorewall dump' to be able to help. See http://www.shorewall.net/Support.htm for instructions. -TomI've attached the results of 'shorewall dump.' I successfully pinged out (Google.com) eth2, brought up ppp0, successfully pinged out ppp0, and then attempted (unsuccessfully) to ping out eth2. Thanks in advance to anyone who is able to take a look at it. I received some "RTNETLINK: invalid argument" errors when executing the dump. Just scanning the results of the dump, I didn't see anything related to ppp0. I DID see some things in the iptables related to connectivity state (ESTABLISHED, RELATED). I don't understand how those could be in there, since I haven't entered in any new rules for Shorewall yet (other than ACCEPT all). Before using Shorewall I had iptables set up with connectivity state rules, but I did an iptables -F and an iptables-save before rebooting and Shorewall starting. Don
