I am replacing a bunch of FreeBSD vpn/fw/routers with a Linux based system. I have run into a situation where if I ping our HQ the response comes back on a different interface than what the request went out on. FreeBSD is happy and says it got the response, Linux is not and gives no indication it got a response. So is FreeBSD wrong or is Linux wrong? Or is there some sysctl I can fiddle with on Linux to make it see the response. This happens with the iptables set to accept on all chains. Thanks again for your indulgence. I googled this and didn't find anything germane. -- "They that give up essential liberty to obtain temporary safety, deserve neither liberty nor safety."
