Hello i am sick and tired of intervally changing operators and ip addresses for my production environment... ive known for a long time that i can do NAT but i am a little bit worried on the load it would cause on the firewall and then again how efficient and easy to maintain it would be. i have a half a C class of Public IP addresses of which about 70 are very active, at best the bandwidth continuous capacity consumption reaches up to 800kb/sec now i have SuSE 7.3 with the latest patches (kernel is the default that comes with the installation) and i intent to use SuSEFirewall 2 on a dual pentium 450mhz with 128mb ram now the question is how can i do so that i have about 40 servers with private addresses in the inside with all sorts of services starting from ftp, telnet, ssh, dns, pop, smtp, imap, stream, http, sms, terminal services, pptp, etc etc how can i configure about 128 IP addresses with NAT to private internal addresses to all ports and port restrictions and what is the most feasible setup regards O.
