IPSec MTU Some ISPs require a setting of e.g. 1492 (or other value). The default

1500 is the most common and you usually don’t need to change this

unless otherwise instructed. Accepted values are from 100 – 1500.

This is the starting value that is used for the MTU when the IPSec tunnel is

installed. It speciﬁes the maximum IP packet length for the encapsulated

AH or ESP packets sent by the router. The MTU used on the IPSec connec-

tion will be automatically adjusted based on the MTU value in any received

ICMP can't fragment error messages that correspond to IPSec trafﬁc initi-

ated from the router. Normally the MTU only requires manual conﬁguration

if the ICMP error messages are blocked or otherwise not received by the

router.

Xauth Enable Extended Authentication (XAuth), an extension to the Internet Key

Exchange (IKE) protocol. The Xauth extension provides dual authentication

for a remote user’s Motorola Netopia® Gateway to establish a VPN, autho-

rizing network access to the user’s central ofﬁce. IKE establishes the tun-

nel, and Xauth authenticates the speciﬁc remote user's Gateway. Since

NAT is supported over the tunnel, the remote user network can have multi-

ple PCs behind the client Gateway accessing the VPN. By using XAuth, net-

work VPN managers can centrally control remote user authentication.
