I have a pix 501 configured with the default access rules and no AAA or filter rules defined. I've been using the pix for serveral months and am able to access any site through it, except for tigerdirect. I get 'the operation timed out' alert from my browser. When bypassing the pix, tigerdirect loads instantly. Any help would be appreciated.

What happens when you do a nslookup for tigerdirect on your computer?

Server & ip address show my isp and my own ip.

Non-authoritative answer shows:

Name: Addresses: 199.181.77.55, 199.181.77.52, 199.181.77.56, 199.181.77.54, 199.181.77.53

tracert tigerdirect.com

I get a request timed out over and over. Each line takes about 15 seconds for it to time out. This is true for any site it attempt to tracert though, not just specific to tigerdirect.

Telnetting to does not go through on port 80 (time out). Every other site i try connects normally..

fixup protocol http 80 is being used. I entered the command and then checked the running configuration, so I'm not sure if it was enabled before. Sorry for the noob question, but after typing a command, does a simple 'refresh' configure the pix or are there other steps required to run the settings that are entered?

I find this a very odd problem, that it is only one site. And its not like i'm 'banned' from tdirect because I can access it when not using the firewall. Any other recommendations would be helpful.

actually, I was going to ask you to temporarily disable the Fixup Protocol http (no fixup protocol http), refresh the configuration, and try again. I've seen a couple of instances where web sites get blocked by the security algorithm, although it's rare.

Ok, disabled that feature, refreshed and still the same result. Not a bad idea though.

And you definitely don't have any access-lists or filters that may be preventing you from getting to those IPs , right?

Try turning up the logging and then attempt connection to tigerdirect. Maybe something will show up in the logs that gives a clue.

I am still having trouble accessing this site. To answer normntwrk, it is not a DNS issue, because typing in that IP still produces the same result.

brontosaurus - Nothing out of the ordinary shows up in the logs. Nothing below a 6. I get this line when attempting to connect:

built outbound tcp connection 262777 for outside:199.181.77.35/80 (199.181.77.35/80) to inside:192.168.1.130/1878 (xx.xx.xx.xx/3178)

Like i said before, It is TigerDirect (199.181.77.35), and I also found that their affiliate Global Computer (199.181.77.85) does not work either. No problems with any other sites.

Something I found out today, a few minutes after logging into PDM, tigerdirect.com loads. With PDM open, the site will continue to load and works normally for about 5 minutes until it goes back into timing out. Tigerdirect.com is accessible through all computers on the network during this time.

This leads me to believe maybe something is temporarily turned off while logging into PDM. Does anyone know if any settings in the PIX are changed while logging into the PDM? Does it have something to do with a secure connection? Please any help is appreciated.
