I have a redhat linux gateway which works as gateway,dns,dhcp and firewall for my lan.
It has two nic, one wiht outgoing static ip and one internal connected with static ip. since last few days, internal one goes on dynamic ip. this create problem, my destops stop connecting to internet. this is happening since last few weeks and with regular interwals of few days. To resolve this i have to assign internal nic with static same ip again and reastart netwerok service and named from /etc/init.d.
Pleaset help to resolve this issue.
