yes i want to map two wan ips (from the same subnet!!!) to one single internal ip

hi!

i want to forward the wan x.x.x.202 and x.x.x.203 to 192.168.0.2

the 192.168.0.1 -> is the lan ip of the asa 5505

how can i configure a second ip ont the asa interfaces? they are in the same subnets....

i cannot assign a secondary ip to vlan2....

my config sofar:

ciscoasa(config-if)# sh run

I see , you are using x.x.x.202 outside interface ip for port forwarding towards 192.168.0.2 .. fine.., the easiest way around it is as Marwan suggested , give 192.168.0.2 host a secondary IP address in tcpip config like 192.168.0.3, then create static nat using your second public x.x.x.203 and nat it to 192.168.0.3

nat (inside,outside) x.x.x.203 192.168.0.3 netmask 255.255.255.0

and respective acl and service ports.

This will be the easiest way to do it.

hi

nat is not enabled... can i do this anyway?

Here:

static (inside,outside) tcp x.203 www 192.168.0.5 www netmask 255.255.255.255

static (inside,outside) tcp x.203 https 192.168.0.5 https netmask 255.255.255.255

the 192 net is a 252 so i had to create a new one

but its still not working...

thansk for the info

but when i do this for the 192.168.0.2 and then for the 192.168.0.4 i get

ERROR: mapped-address conflict with existing static

TCP inside:192.168.0.4/80 to outside:

simple yes

i did it with the same private ip

works

thanks!

Congrtulations!

could u tell what u have done then worked?
