CUPS client 7.0(1.13056)
Windows 2003 VPN (PPTP/GRE)
The CUPS client works wonderfully on LAN/WAN, but when using VPN, it logs in and shows status, but LOGON SERVER and LDAP SERVER show unavailable.
When try to start a chat, says 'An Instant Message could not be started because the network appears to be disconnected.'
Interestingly, Presence phone (UPC[username]) and TFTP are green.
Routing works and more, so, the LDAP server is in the same L2 network as the VPN server's interface.
I read through several posts regarding this issue, including:
- validate profile is set to Cisco SIP Proxy TCP Listener (this was under App --> CUPS --> Settings for v7)
- validating our FW does not do SIP inspection (though moot, since our FW isn't the terminating point for the VPN tunnel, so it's all encapsulated through the tunnel)
- acknowledge the known bug/caveat (CSCsf26033) in the CUPSr7 release notes which says to use TCP for the profile.
I even used Wireshark to validate the frames were TCP and the servers are talking and they appear to be!?
Yet, RED for both those servers.
I'm stuck and could use some suggestions.
(Love this site, by the way)
