SMC Networks Barricade BR14VPN - Manual (Page 63)

F. I am having problems establishing a PPPoE xDSL WAN connection
Some ISP’s require you to enter the domain name in addition to your username and
password. For instance, for SBC Global, enter [email protected]. For Ameritech users,
enter [email protected]. BellSouth users may need to enter [email protected]
and Mindspring subscribers enter [email protected]. Lastly, Earthlink subscribers
should enter either [email protected] or ELN/[email protected].
G. Can I use this router with AOL DSL?
This is true in most scenarios. Please verify with AOL that your particular connection type is
PPPoE. If yes, then the SMC VPN Broadband Router should work with your WAN connection.
Follow the normal procedures as described in Section 7.3 of this manual, but while doing so,
set the MTU value to 1400. AOL DSL does not allow for anything higher than 1400.
H. IPSec VPN Configuration
When setting up IPSec VPN tunnels between two BR14VPN, BR18VPN or one of each, it is
imperative that you:
a) Use the same pre-shared key between two endpoints
b) Configuring matching IKE and IPSec proposals between two endpoints
To successfully create IPSec or IKE Proposal lists, you must configure the desired DH Group,
Encryption/Authentication Algorithms, and Lifetimes, and then select the appropriate
proposal ID and click the “Add to” button to add the proposal to the Index.
I. I have authentication problems with the L2TP or PPTP VPN Server
The Router’s VPN Server will reject VPN clients that attempt to connect without the proper
credentials. In the same token, if the VPN client is configured to connect only to encrypted
networks, the client will not connect to the Router’s VPN Server if it is configured for PAP or
CHAP Authentication.
If you have configured the Router’s VPN Server to use the PAP or CHAP Authentication
Protocol, MPPE Encryption cannot be enabled. Therefore, you must configure the VPN client
to connect the Router’s VPN server without requiring encryption. By default, Windows VPN
clients require encryption. You can go into the properties of the VPN connection and disable
this requirement.
