10/100 Autosensing Problem with a MicroRouter 900i/1000R
You are connecting a MicroRouter 900i (or 1000R) to a 10/100 autosensing hub. The MicroRouter and the hub cannot see/talk to each other.

Adding Memory to Your IntraPort 2 VPN Access Server
Some earlier builds of the IntraPort 2 VPN Access Servers may have only 4 MB SDRAM, which will not support software versions 5.x or later. If this is the case, you will need to upgrade the memory on your server in order to use the latest software versions.

Adding Memory to Your MicroRouter 12/22xx
Beginning with software version 4.5, all 12xx and 22xx series routers (1200i, 1220i, 1250i, 1270i, 2200R, 2220R, 2250R and the 2270R) may be upgraded with a 72-pin dual-banked (double-sided) FastPage mode SIMM up to 4MB.

Adding Memory to Your RISC Router 2800i/3400R
With the advent of system software v4.0.0, additional memory can be added using a 72-pin FastPage mode SIMM of 2, 4, 8, 16 or 32MB.

Adding Memory to Your RISC Router 4000S
Upgrading your 4000S system software to v4.0.0 will allow you add more memory to your RISC Router.

IP Fragmentation and MTU Path Discovery with VPN
The IP protocol family was designed to use a wide variety of transmission links. The maximum IP packet length is 65000+ bytes. Most transmission links enforce a smaller maximum packet length limit, called maximum transmission unit, or MTU, which varies with the type of the transmission link. The design of IP accommodates link packet length limits by allowing intermediate routers to fragment IP packets as necessary for their outgoing links.  The final destination of an IP packet is responsible for reassembling its fragments as necessary.

Ports and Protocols Necessary to Pass Through a Firewall with your LAN-to-LAN and Client VPN Tunnels
Forwarding VPN traffic through a Firewall depends on what Compatible Systems IntraPort Client software you are using, what type of transforms are specified, and/or the type of LAN-to-LAN tunnel being used. Both IP protocols and TCP/UDP ports must be opened in the Firewall.

Transitioning from STEP to IKE IntraPort Client Software and Upgrading from 4.x to 5.x IntraPort VPN Access Server Code
Transitioning VPN users from STEP to IKE is not as bad as you might expect. There are very few changes which need to be made, the exact number of which depend on how your authentication is currently being performed. Users in any given group can migrate as they get the 3.x Client installed, meaning that 2.x and 3.x users can use the same group configuration concurrently.

Upgrading Your RISC Router 3000E from v1.1.3 and Earlier
In order to upgrade the 3000E's system software to v1.2 or higher, you must first reconfigure the device's programable internal memory structure.

Un-numbered Frame Relay
With the release of software, v4.4.10, support for IP un-numbered Frame Relay is included.
