People, If iptables are setup to only accept ssh logins from particular IPs, how do people login when they are on the move and have a DHCP allocated IP? I thought I could do this by sending a mail (from the remote DHCP IP) formatted in a particular way, to a particular user on the destination server which would then be processed, which would then cause a change to the iptables setup. However, I assume other people have had to solve this problem and I don't want to re-invent wheels . . Suggestions appreciated!
