http://shorewall.net/MultiISP.html For incoming connections this works great. I've used it a couple times while migrating from one ISP to another, while preserving connections through the old ISP to individual incoming connections and ipsec tunnels until they're updated. If the ISP is unreliable, you're going to be losing incoming connections or causing delay until the issue is resolved (by switching ISPs or otherwise). Maybe adding a 2nd DNS "A" record to the address with the 2nd ISP is good enough. If your issue is with *outgoing* connections, you probably need another tool in addition to shorewall. Maybe like this, but I haven't used it. http://shorewall.net/MultiISP.html#lsm Justin _______________________________________________ Shorewall-users mailing list Shorewall-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/shorewall-users
