Static route mapping in ASA cannot go out

Posted on 2010-11-17
Last Modified: 2012-05-10
I have configured the ASA and the DHCP client can access the internet through it. However, all my servers couldn't work and I believe there may be something wrong on my static mapping. Actually, on the server, I could ping a website (eg. and get reply. However, when I open the IE and visit the site, it will timeout.

Any idea ?

One interesting thing, when I remove the static map for a server, it could visit other website. If I put it back, it doesn't work again.
 static (inside,outside) a.b.122.164 netmask

Actually, the ASA have worked for a long time and it doesn't work recently after cooling problem in the server room which caused all servers to shut down automatically. But that shouldn't affect the routing in ASA.

Any idea why does it happen, or I have missed something on the static mapping ?

Your routes in the config are correct. I'd get the firewall serviced/replaced immediately. There's no telling what else is happening or what other traffic is being allowed in thats' not supposed to get in.

Might be some tcp mss issue. Your answer is hidden in syslogs. Simply enable syslogs in asdm or to an external syslog, start viewing logs live, then in the search or filter line, type your servers IP so filtering will be narrowed down, then try to enter a website, and ping a website.

If you dont get any logs, then somethng is wrong with server, maybe proxy settings
If you get any logs originated from server, paste them here

ONe thing I notice is the Global is set to "Interface". When defining statics, that have to proxyarp on that interface, I have found that the global has to be a specific IP. Since you have 30 IPs in that subnet, you probably have enough. Set "Global (outside) 1 a.b.122.163 netmask " or similar and that should help.

Ultimately, I would do as MrHusy suggests - look at the log and find out what it is saying about traffic

How to enable the syslogs with Cisco CLI ? Any guideline  ? Can I just view it on the Cisco Console ?


Accepted Solution

from cli:
logging enable
logging timestamp
logging buffer-size 16000
logging buffered informational
logging asdm debugging
logging host inside a.b.c.d     (syslog server, if you have one)

After you add the above, open ASDM, go to monitoring tab, select logging, realtime log, and click View

Apperantly you found out the problem from syslogs, since you accepted boilermaker's answer, which was MY suggestion. And you shared points to someone who told you to service the firewall which has absolutely 0 meaning.

Please respect next time

Clearly MyHusy want the points, genius that he is. He feels he needs the points  because he thinks he is the only one who would consider using the log. I dont need the points. let him have them. I'm just here to help.
