We are using Cisco ASA 5540 , we configure ipsec vpn on that. when they connect at our network through VPN, they (client side) are able to access our desktop through a software that we are using for remote support called Remote admin and using port 4899. But as per as security concern now we block 4899 port access, we implement access-list but it is not working, may be there is some tricks. Can you help me out to block that port over vpn to access our network from client side.
