Re: Internet adsl modem ---> Cisco 515e V7 ----> Server (dns-web

i meant

lets say u have three server on the inside

first the inside ip will be for eample

192.168.1.1 /24

server 192.168.1.10

server2 192.168.1.20

server3 192.168.1.30

and u have the above address u want each one to be mapped

based on ur config u need to do the folloiwnf

nat (inside) 1 192.168.1.0

global (outisde) 1 interface

static (inside,outside) 82.70.83.83 192.168.1.10 netmask 255.255.255.255 0 0

static (inside,outside) 82.70.83.84 192.168.1.20 netmask 255.255.255.255 0 0

static (inside,outside) 82.70.83.85 192.168.1.30 netmask 255.255.255.255 0 0

and change the inside ip addrees

this will make static ip to ip maping (nating)

and keep ur ACLs as u want to permit what u want

good luck

please if helpful rate

Re: Internet adsl modem ---> Cisco 515e V7 ----> Server (dns-web

first if u gonna configure it like this u will lose IPs fo interface and so on

just put one of those IPs on the dsl setup for the outide or dialer interface

an others make them through static nat

easy

ststic (inside, outside) [public ip] [rivate ip] netmask 255.255.255.255

do the above for each ip

and mak an acl permit traffic from any distened to the public ip address either any port or for secific port

then apply it inbound on the outside interface

thats it

good luck
