I'm out of the office at the minute but will extract them later today.
This has always worked before, the default route is in the main table (maybe not clear before) and is used so that the box can route local packets out. Your example (below) would do the same except skip the fwmark rulesNot exactly. In my example, to skip the fwmark process the destination address must be known by the main table. And you dont need to treat your essential routes in alternative tables (only default gw). For this reason, you couldnt use a default gw in main table (*my example*).
Ok, misread that and still had a default in main in my head. Makes sense now
Neither do I? The only thing I can think of is a new kernel inadvertently installed by a colleague but without doing a reboot. As it all worked fine until it was rebooted (to physically move it). Also, oddly before I left last night, it was occasionally connecting when doing some testsBut, i still not sure why your setup has stopped working.
I guess I don't need to, I wanted to only mark new connections and the use save-mark and restore-mark to mark further packets. The plan is that each new connection is marked using the statisic module and routed based on the mark.Yes, sorry when doing the example missed off the -m state --state NEW bit... I still find it strange that recently packets I'd expect to be in the NEW state are ESTABLISHED. eg doing ping blah ping blah results in the first outgoing packet being NEW, but the second ping is ESTABLISHED, surely this is a bug?Why you need to work with connection STATEs in firewall MARKs?
It still seems like a bug that subsequent independent connections are labelled as ESTABLISHED?
Tell me more about your configuration. I can check your firewall confs if you open your ssh access for me (send me account in pvt - if you like).
