I am using MS VPN/PPTP client. This client works fine from home but not at the office. At our office, we have a 192.168.2.0 /24 subnet. We have two DSL connections from the same provider. Both of these DSL connections are in the same Class C subnet. One DSL is used for the office users and one is used for a completely, separate/isolated test environment. I need to be able to PPTP into the test environment fw (71.x.x.50) from the local office lan. I am sitting behind a 2811 using CBAC for outbound traffic and an ACL for inbound traffic. I can't even telnet to port 23 and the log only shows this generic message:
002027: Mar 4 17:27:19.861 CST: %FW-6-SESS_AUDIT_TRAIL_START: Start pptp session: initiator (192.168.2.120:51094) -- responder (71.x.x.x:1723)
002028: Mar 4 17:27:42.226 CST: %FW-6-SESS_AUDIT_TRAIL: Stop pptp session: initiator (192.168.2.120:51094) sent 364 bytes -- responder (71.x.x.x:1723) sent 352 bytes
Here is my config. What should I change, please?

ip inspect name Outbound icmp router-traffic
ip inspect name Outbound pptp audit-trail on timeout 3600

No-nat ACL for site-to-site VPN but these VPNS go out a separate private line T-1 interface.
