Microsoft uses an embedded L2TP/IPSEC VPN implementation. In order to use the Microsoft standard VPN client, one has to disable the IPSEC on the PC. Please refer to Microsoft help to perform this operation.
9.1 Questions and Awnsers
What is the difference between SMCBR14VPN and SMCBR18VPN?
The SMCBR14VPN has 4 LAN ports and the SMCBR18VPN HAS 8 LAN ports. There is no other difference. The firmware is the same for both.
How many tunnels can be configured?
40 IPSEC tunnels
5 PPTP tunnels
5 L2TP : Important, not L2TP/IPSEC, but just L2TP alone
In total: 50
Do I need two routers to establish a VPN connection?
No. PPTP tunnels and L2TP tunnels can be created with the built in Windows VPN tools Although it is possible to use the built in IPSEC of Windows, it is much easier to use IPSEC client programs.
There are advantages when using 2 SMCBR14VPNs, especially when connecting two remote offices:
No configuration on end clients
End clients will just “see” the other office as if it was located on the same LAN. Please remember that the two routers should have different LAN addresses.
Can the SMCBR14VPN act as a PPTP client?
No, it can only act as a PPTP and L2TP server
Can I use domain names and dynamic VPNs?
Yes. The SMCBR14VPN supports Dyndns on the WAN side.
As Peer IP address for the IPSEC tunnel, a domain name can be used
Dynamic VPN is supported, i.e. the router will accept a VPN connection from any IP address with valid parameters
