Simple static nat to internal servers

Don Weston

Level 1

I have been trying to configure 2 static nat

rules to allow traffic to pass to a internal server for http and RDP services

here is what I currently have working:

interface eth 0/0 "extranet"   IP: 64.xxx.xxx.148

interface eth 0/1 "intranet"    IP  10.xxx.xxx.1

WEB/RDP SERVER           IP  10.xxx.xxx.13

nat-control
global (extranet) 1 interface
nat (intranet) 1 0.0.0.0 0.0.0.0

route extranet 0.0.0.0 0.0.0.0 64.xxx.xxx.145 1
access-group outside_in in interface extranet

access-list outside_in extended permit icmp any any  'for troubleshooting purposes

so far this works fine, I've added variations of access-list/static rule examples I've seen posted to try and create the routing to the internal server but nothing seems to work.

The server in question does ave access going out and  I can access the web abd RDP services from internal addresses.

a little nudge in the right direction would be greatly appreciated.

Sorry, I should have mentioned I'm running ASA Version 8.0(4) as well.

If you are presenting the internal web server on it's own address -

static (intranet,extranet) 10.xxx.xxx.13 10.xxx.xxx.13 netmask 255.255.255.255

access-list outside_in permit tcp any host 10.xxx.xxx.13 eq http

access-list outside_in permit tcp any host 10.xxx.xxx.13 eg 389

if you are presenting the web server a different address eg. 64.xxx.xxx.150

static (intranet,extranet) 64.xxx.xxx.150 10.xxx.xxx.13 netmask 255.255.255.255

access-list outside_in permit tcp any host 64.xxx.xxx.150 eq http

access-list outside_in permit tcp any host 64.xxx.xxx.150 eg 389
