Good Evening -
I have approx. 25 x 1450 gateways on embedded GAIA_R77.20.70 - configured with an external WAN interface and an internal switch - LAN1_switch. To get the switch to pass packets to the WAN interface routing was enabled in
# /proc/sys/net/ipv4/ip_forward by setting the value to <1>. Good to go. BUT, i am unable to get it to survive reboots! i also tried enabling it by # sysctl -w net.ipv4.ip_forward=1. Again, reboot killed it.
To make it persistent and survive reboots in full GAIA, or other 'full' distro, I would edit /etc/sysctl.conf , but this file does not seem to exist in the embedded version.
Anyone else come across this snafu - and found a fix? Or anyone know if an equivalent sysctl.conf file exists in embedded GAIA?
