Was zeichnet einen Sarian Router besonders aus?
- SAR/OS _
Extremely fast resolution of unforeseen problems. Ability to re-engineer to accommodate unusual requests in larger projects.
- Reliability _
Sarian hardware has developed a strong reputation for 24x7x365 reliability with existing customers.
- Dual Sim _
Extra layer of backup
- VRRP+ _
Sarian patent - Patented extension to VRRP (RFC 2338) which probes for a logical connection with the host.
- ScriptBASIC _
enables customers to customise their Sarian products
- ISDN NT Mode _ Fast and seamless conversion of ISDN based terminals to ADSL or GPRS/UMTS
- REMOTEMANAGER _
Remote configuration and firmware updates. Ability to manage large quantities of routers in the field.
- Legacy Migration _
In built support for a wide range of legacy protocols (Synchronous & Asynchronous Serial / X.25 / X.28 PAD / TPAD etc)
- SLA Policing _
(with REMOTEMANAGER) – Allowing customers to produce reports which highlight non conformance with network provider service level agreements.
- Support for the Datawire VXN protocol _
Only router capable of supporting VXN – used in the financial marketplace.
- Deeply embedded RF Module

Memory stick cloning
The ability to securely clone or configure Sarian routers using a USB memory stick avoiding the need to use a laptop on site for configuration.
Extensive support for telemetry applications
Using ScriptBASIC, a Sarian unit can read and control a wide range of local telemetry devices such as temperature sensors and relays. The results can be relayed to an industry standard OPC host.
Anwendung:
- The user has prior knowledge of configuring both the Windows PC and the Sarian
Router for connection to the Internet or other wide area network
- Both the Sarian and the Windows PC are assigned a public (not a “natted”) fixed IP
address on their public interfaces
- IPSEC is to be used in “main mode”
- IPSEC tunnelling is used
- The Windows PC is NOT a member of a domain
- Pre-shared keys rather than certificates are to be used
- IPSEC with Windows only works correctly in Sarian firmware version 4.586 or later

Layer 2 Tunneling Protocol (L2TP) can be used to tunnel layer 2 frames and thus provide remote access to a private LAN.
IPSec is a standard for encryption and security, running L2TP over IPSEC can therefore provide secure encrypted remote access to a private LAN. This is commonly known as a VPN or Virtual Private Network connection.
Microsoft Windows XP TM and Vista TM provide a VPN client that is capable of running L2TP over IPSEC. This application note explains how to configure a Sarian router to act as an L2TP/IPSEC VPN server for a Windows XP TM or Vista TM client.
This solution works even if the client does not have a public IP address i.e. is connecting from a behind a router running NAT.
Configure a Sarian Systems IR2420 to act as a L2TP (Layer 2 Tunnelling Protocol) over IPSEC VPN Server. Multiple remote hosts will open a VPN tunnel between themselves and the VPN server. L2TP will run over the IPSEC connection and the PPP connection will be negotiated over the newly established L2TP Pipe.
The remote PC’s will be running Microsoft® Windows™ L2TP over IPSec VPN Client with a Dial Up Networking connection to an ISP. This Application note will also take the user through the Microsoft® Windows™ Connection Wizard.
VRRP bedeutet dass eine IP-Adresse zwischen 2 Units „floaten“ kann wobei eine davon priorisiert werden kann.
The Sarian VRRP implementation is fully RFC complaint and will work with other vendors VRRP implementations providing they are also RFC compliant.

Using a Single VRRP IP Address: This uses a single Virtual IP address shared between two units
This will mean that the IP Address 10.1.4.254 is not assigned to any one unit but floats between them depending on which is the VRRP master router. If both ETH0 interfaces are connected to hub/switch along with a client then the client will be able to always see a router at the 10.1.4.254 address.
Unit_1 has a priority of 110 so should become the VRRP master router over Unit_2 which has a lower priority of 100.
This is the simplest configuration but it is not generally adopted as it means that you can only attach to the unit that is the VRRP master at any one time which is no good for administration and monitoring of both the units.
