    I have a very simple site-to-site ipsec VPN connecting two sites with single subnet at each site. The pings and traceroutes between the end stations on either site work just fine. However, Remote Desktop, PC Anywhere does not fully work. Only partial screen appears in case of PC Anywhere whereas only black screen is displayed for Remote Desktop. Bandwidth is not the issue as enough is available. RD and PC Anywhere have been locally checked and they are working.

    There are no access lists configured on the routers except the ones required for the crypto interesting traffic. No split-tunneling for Internet access is involved either. I have looked at the firewall on end stations, etc and there is none. Also, all communication is on IP and DNS is not involved.

    Platform: a couple of Cisco 1811 routers with dual ethernet ports. Each router has one local LAN interface and the other interface goes to the Internet gateway.
    I am already running several such VPNs at other sites but this one is behaving so abnormally (not at IP level but TCP connections).

    Could someone shed some light on what could be the problem?
