I'm using an AWS instance to relay some traffic to an onsite mail server. A few days ago, sometime between Sunday and today, I noticed that it wasn't actually forwarding. The AWS instance is running archlinux, and I'd updated and rebooted recently. I scratched my head for a little while before I figured out that /proc/sys/net/ipv4/ip_forward had been set to 0 instead of 1, which was new and unexpected. Turning it back on, everything worked as before.
I fixed it persistently by adding a file in /etc/sysctl.d/ to set net.ipv4.ip_forward = 1 Thanks upstream peoples! -- Russell Senior [email protected] _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
