we have one https ulr of one of our customer...which is not opening from office... This URL is hosted over internet...
Normally we open url in two way...via enabling proxy & other is disabling proxy (just to following diff paths).
Access using any of above method does the patting over PIX 535 firewall (different pat)
This https url is not opening from Windows 7 Machines using without proxy.... but using proxy it opens.
However doing without proxy we can able to telnet to destination over port 443. that confirms we have necessry access from our source --pix to destination..
but still web open is not opening...
Yes from Win XP you use any method this url opens....
Win 7 from outside office net / other office where we have ASA firewall it opens..
Is their anythig to do with PIX...../ any method to drill this issue.
Follow this link and add the fix to allow mss-exceed.
No need to change the MTU on the firewall.
