I have a problem with PPTP on PIX515 with software 6.3.3 It is connected to Internet. The problem is that in some moment no PPTP sessions can be established. At this moment the following wtring is logged
Feb 02 2004 08:33:10: %PIX-7-710005:
TCP request discarded from internet_ip_addr/3053 to outside:outside_intf_addr/pptp
It happens without any regular period.
The problem can be solved by issuing commands
no vpdn enable outside, vpdn enable outside.
I don't think that it is an atack as the number of connections is not more then usually.
I found an old bug CSCds21095 that seems to be the same, but it is already resolved in 6.1.3
Is it possible that it reappeared?
Also there was a question in this forum but with no answer:
