Router - Virtual Private Networking

NN40011-047 Issue 1.2 BCM50 Rls 6.0 11

The above diagram shows the information required for the VPN Branch setup

from switch A’s perspective:

 “My” IP Address is the WAN IP address issued by the ISP (Internet

Service Provider) to switch A

 Secure Gateway Address is the WAN IP address issued by the ISP to

switch B

 Local IP Address Range is the range of IP Addresses used on the LAN

connected to switch A

 Remote IP Address Range is the range of IP Addresses used on the

LAN connected to switch B

If a PC on switch A requests information from a PC on switch B, switch A will

initiate a VPN connection via switch B’s Secure gateway Address. Therefore,

the two LANs can communicate via the global (WAN) IP addresses specified.

From switch B’s perspective, the set information is the same but the

terminology is reversed, i.e. switch A’s “My” IP address becomes switch B’s

Secure Gateway Address and switch A’s Local IP Address Range becomes

switch B’s Remote IP Address Range etc.

Content ID & Type

Content ID and Type are extra security features that act as extra levels of

security for incoming VPN requests. They do not replace any of the possible

encryption methods (ESP, AH).

The options for type are:

 IP – IP address of a computer or BCM50 Integrated Router router

 Domain (DNS) – A designated domain name

 E-mail – A designated e-mail address

Note: The Domain name and e-mail options do not have to actually exist and

are purely referential.

When using this feature, both local and remote (peer) Content ID and Type

will have to be specified and mirrored for either end of the VPN connection.

For example, referring back to the diagram in the VPN Branch Relationships

section, the Content ID and Type fields on switches A and B could be as

follows:

Field

Switch A

Switch B

Local ID Type

E-mail

DNS

Content

[email protected]

www.iteluk.com

Peer ID Type

DNS

E-mail

Content

www.iteluk.com

[email protected]

This information has to be agreed by the BCM switch administrators of both

BCM50 Integrated Router switches.
