why can't access same websites on restricted PC?

CCCC_12345
Level 1
Level 1

Has ASA5510-K8 as firewall, has access rules setup for restricted PCs:

  • Source: IP range of these PCs 192.168.x.0/24
  • Destination: publicPC
  • Service: tcp/http
  • Interface: inside
  • Action: permit

On those PCs, users can only browse the websites that are in favorites, but some of them are working, some are not.

Test on unrestricted PC, websites that can’t be accessed from public PCs can be access on regular PCs , either by address or IP.

Checked GPO setting, don’t see anything wrong there.


Can anyone please tell me what wrong and where should I start troubleshooting? Thx.

Hi,

on unrestricted PC do a ping  www.xxxxx to get the IP of the site not working on restricted PC then add an entry in the hosts file for this url and flush the dns cache of the PC and try browsing.If it is working then it is a DNS problem and you'll have to modify your ACL for DNS queries.

Regards.

Alain
