Hi I have USG 100 and strange problem. It seems that name resolution is not functional over VPN but sometimes I am able to connect via RDP to the machines in the network. So the situation is like this : when I connect with L2TP I am able to RDP only to the PCs that are not in the domain, and only with IP! To the one already in the domain I cannot connect. When I try with netbios name I get error : RDP cannnot find computer "PC". when I try with IP i get cannot connect to the computer because 1. RDP not enabled, 2. PC is shut down ..... When I try with FQDN I get the same as with the IP. I can ping with IP and some servers with name ? With PPTP,SSTP VPN ( that microsoft server terminates) I can connect to that PC so it is not the problem regarding disabled access to the pc, and pc is not turned off.
Hi. Is RDP service active on clients? Do l2tp clients get Domain DNS addresses with DHCP? Are they part of "remote destination", for the l2tp clients? Is DNS traffic allowed from L2TP to LAN X? Do DNS servers accept dns queries from outer addresses?
