Important /proc Security Files
/proc/sys/net/conf/default/proxy_arp
- Boolean – 0 or 1 toggle off and on
- This should really be set only on the interfaces that need it rather than default
- Determines whether interface responds to ARP's for IP addresses other than its own
- Not needed for NAT
- May be needed when RAS VPN clients use virtual addresses on an internal network directly connected to the gateway
