Cisco Cisco Aironet 340 Access Point-RP-TNC Guía Para Resolver Problemas

Select the wireless client adapter that you use to connect to your Base Station unit (in the example
shown in Figure 2, Local Area Connection 3).

2. 

Under MTU Options, click the 1400 radio button, and then click OK. This causes your PC to
transmit packets with 1400 bytes as the maximum. Therefore, the additional IPSec header is
accommodated, but the 1518 byte normal maximum size of an Ethernet packet is not exceeded.

3. 

Note: The statement that "MTU changes can affect your PC's performance on the network" refers to the fact
that because of the smaller MTU size, two packets are required to send the data previously contained in a
single non−encrypted frame.

For details on how to configure your Base Station unit for PPP over Ethernet (PPPoE) and Cable/DSL, refer
to Configuring the BSE342 and BSM342 Base Stations.

Note: Point−to−Point Tunneling Protocol (PPTP) is not supported

Note: Install the wireless card before the VPN client is installed. If necessary remove both, then reinstall the
card followed by the VPN. Although this was an issue in the Cisco 2.x release of the VPN client, it was fixed
in the later revisions.
