i had the same problem; it has nothing to do with 5 c classes of ip or in my case 1 IP on the outside for X number of internal users. Either something is wrong with the pix 6.2 Code, or it has very aggressive timeouts. Some of the problems you will see are short time outs on downloads, AIM dying without explanation, and people not getting patted when going to the internet.
this fixed my problem... (the timeout XLATE, didnt not fix it, but its there because i was not cool with the default of 3HRS) timeout xlate 6:00:00 timeout conn 12:00:00 half-closed 0:10:00 udp 0:02:00 rpc 0:10:00 h323 0:05:00 sip 0:30:00 sip_media 0:02:00 even if you have the default 0:00 (never timeout) it still does timeout like in one minute.. also nats dont work (really patting) Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=45471&t=45465 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
