Sitting behind a Cisco 7206 perimeter router and 2 load balanced Gauntlet FWs on Solaris, internal client browsers cannot access a few distinct, unrelated web sites. Either 403 errors (Netscape) or blank page (IE) returned. Our upstream provider is unable to access these particular sites as well.
>From an unadvertized host in our DMZ (directly off the perimeter router) I am able to access the sites 80% of the time. Had a similar problem a while back when it was determined that a device hosting the remote web server was limiting MTU size. Our upstream provider put in place a workaround to match max MTU size between us and remote site. 1) Does this sound like an MTU-related problem or more a DNS issue if remote site is attempting to do resolution to determine if we are coming from a particular domain? 2) Is there anything we can do at our site either on router or firewalls to at least give us the same, albeit less-than-stellar, results we get from our DMZ? If more info is needed I will attempt to supply, but cannot give too many specifics. Any thoughts appreciated. Joe Volk __________________________________________________ Do You Yahoo!?
