Fragmentation Threshold This value specifies the
maximum size for a packet before data is fragmented
into multiple packets. If you experience a high packet
error rate, you may slightly increase the Fragmentation
Threshold. Setting the Fragmentation Threshold too low
may result in poor network performance. Only minor
reduction of the default value is recommended. In most
cases, it should remain at its default value of 2346.
RTS Threshold Should you encounter inconsistent data
flow, only minor reduction of the default value, 2347, is
recommended. If a network packet is smaller than the
preset RTS threshold size, the RTS/CTS mechanism will
not be enabled. The Router sends Request to Send (RTS)
frames to a particular receiving station and negotiates
the sending of a data frame. After receiving an RTS, the
wireless station responds with a Clear to Send (CTS) frame
to acknowledge the right to begin transmission. The RTS
Threshold value should remain at its default value of
2347.

VPN Passthrough
IPSec Passthrough Internet Protocol Security (IPSec) is
a suite of protocols used to implement secure exchange
of packets at the IP layer. To allow IPSec tunnels to pass
through the Router, keep the default, Enabled.
PPTP Passthrough Point-to-Point Tunneling Protocol
(PPTP) allows the Point-to-Point Protocol (PPP) to be
tunneled through an IP network. To allow PPTP tunnels to
pass through the Router, keep the default, Enabled.
L2TP Passthrough Layer 2 Tunneling Protocol is the
method used to enable Point-to-Point sessions via the
Internet on the Layer 2 level. To allow L2TP tunnels to pass
through the Router, keep the default, Enabled.
