can pix do this?
1.NAT PROBLEM
for instance,pix's public address is 218.242.2.1,its private ip address is 192.168.0.1/24,there is a server whose ip address is 192.168.0.100,if someone in internet want to access tcp ports from 2000 to 5000 of 218.242.2.1,the pix can forward all the traffic to 192.168.0.100?if can,how to do this?
2.VPN problem
the structure is :
INTERNET--ROUTERA--PIX--LAN,both the ip address of inside and outside of the router are public address,and both the ip address of inside and outside of the pix are private address,.but I use NAT to translate the pix's outside ip address to a public address,then can pix act as a vpn server?that means if someone in internet can dialer in the pix with cisco vpn client software?if can,is there any diffirent config in pix or router?in the pix's place,if there is a routerb or vpn3000,can they act as vpn server?
thanks
