Users are not able to connect from the outside.
The VPN address that clients use from the outside is 173.14.170.113
The VPN address on our inside network is 192.168.0.13
I have set up the ASA for my VPN as follows:
access-list acl-out extended permit tcp any host 173.14.170.113 eq pptp
access-list acl-out extended permit gre any host 173.14.170.113
static (inside,outside) tcp 173.14.170.113 pptp 192.168.0.13 pptp netmask 255.255.255.255
When I use packet tracer it shows a drop of the IP gre traffic on an implicit rule that denies any IP traffic even though I have it opened earlier in the access list.
Thanks for your help,

Hi Gary,
did you try adding inspect pptp?

Yeah, there is an inpect pptp added in one of the sections. One other thing is that packet tracer is only dropping on the implicit rule. PPTP passes through just fine.
Thanks for your help,

Hi,
Can you post your full config (without sensitive information) and the output of the packet tracer?

As of 8.3 you have to use inside local address (192.168.0.13) in the ACL.
You also need a static NAT line for GRE protocol. Or I would use a static one-to-one IP mapping.

Hi, is it solved?

Not solved as of yet. Sorry for the delay with getting back.
We are using ASA 7.2(1). Also it won't let me do a NAT line for GRE. The only options are tcp or udp.
How do I assign static one-to-one IP mapping?

Hi,
The Static NAT format is almost the same as the Static PAT configuration you have done for the TCP port.
static (inside,outside)

Thanks for your help.
I added the Static NAT line. static (inside,outside)
The firewall is no longer dropping gre traffic as it was before, however I am not able to connect to VPN.
