ASA 5510 secondary IP on outside

Not being too familiar with the ASA, I have everything configured I need and it is working. The problem now is, I am trying to get an additional external IP address working to point to a new server inside our network. In many other firewalls and even on a PIX I know how to do this, but something does not seem to be working. Here is the scenario:

Existing static IP that is working: xxx.xxx.65.195

New IP address to add: xxx.xxx.65.196

Here is the entire config showing the lines with WVSHAREPOINT which is the internal server we are trying to publish. This site works internally, so it has to be a config error. I simply get a time out when accessing from the outside. Any help would be greatly appreciated.

Re: ASA 5510 secondary IP on outside

Try changing the outside access list to reflect the public IP address and not the internal one :

access-list outside_access_in extended permit tcp any host x.x.65.196. eq https


And also try just simple NAT and instead of doing a port translation :

static (inside,outside) xxx.xxx.65.196 WVSHAREPOINT netmask 255.255.255.255

Re: ASA 5510 secondary IP on outside

I have tried both of these suggestions, with the same results. Timeout on the outside. I assume these were to be used together and remove the old one which I did correct?

Community Member

Re: ASA 5510 secondary IP on outside

Hi Ron,

Change the acl as below as mentioned by Dmitry earlier:

access-list outside_access_in line 1 permit tcp any host x.x.65.196 eq https

Cl xl loc WVSHAREPOINT

Try accessing it after that and see if we get any hitcounts in the acl.

Re: ASA 5510 secondary IP on outside

Yes, try clearing the xlates as Ashu just mentions below; that will clear any old static translations and you should be able to use the new ones. As a rule of thumb you should clear the old ones any time you make a change to the NAT...

Community Member

Re: ASA 5510 secondary IP on outside

Okay, one question... I turned on logging and is this how I view hit counts on an ACL or how is that done?

Thanks again for all your help!

Re: ASA 5510 secondary IP on outside

Hit counts show up when you display an access list.

Run this command:  show access-list outside_access_in

and see if the count of hits at the end of the access list is increasing,

should be something like:  (hitcnt = 10).

Community Member

Re: ASA 5510 secondary IP on outside

Ahh yes, well the hit count on that ACL is showing 0.

Community Member

Re: ASA 5510 secondary IP on outside

That means, the traffic is not even making up to the firewall. We need to check if the traffic is not blocked before it reaches the firewall.

Re: ASA 5510 secondary IP on outside

Anything in the logs regarding that connection?

Make sure you enable logging to send logs; run this : logging enable

Community Member

Re: ASA 5510 secondary IP on outside

Hi,

Also ensure that proxyarp is enabled on the outside. Enter the following command to be sure:

no sysopt noproxyarp outside
