example the simplest topology:
comp comp comp computers in LAN....
publicIP | | | |
=========== server ---+----+----+----+----...
some of comp has private addresses 192.168.... and some of them have
to had public IP addreses.
SNAT+DNAT on server - but some protocols are not well supported [ex.
IP of comp's are set to 192.168.... but on DNAT is translated to IP public.
2. solution - this one of witch we discussing...
IP of comp's are normal public IP, on serwer is routing to this hosts,
proxy_arp is enabled, FORWARD for this comp's are not blocked
I want to be able to set public IP's for computers in LAN. Is any
other solution ? I dont know about it - if you so - please let me know
I am the ISP network administrator.
Thanks a lot.
