Security

The router provides a number of means of providing security on incoming and outgoing traffic on a network. These methods include access password authentication, firewall limiting access to only designated device addresses, private network address translation (NAT) and filtering for both incoming and outgoing traffic.

Configure PPP Security

The PPP router provides support for both PAP and CHAP security access authentication. An outgoing user name, PAP password, and CHAP secret are defined that the router will use when responding to an authentication request from a remote site PPP router.

The cold start defaults for the security user name and passwords are as follows. These defaults will exist when the router is first started before and configuration is entered, and after a Full Reset has been performed. These default values are also set when the router is placed in TFTP Network load mode for upgrading the operating software via TFTP transfers. Care should be taken when upgrading a group of routers that have security levels set.

Default outgoing user name for each remote site when it is defined is the same as the default device name. Default PAP password and CHAP secret are both set to “BRIDGE”.

The complete password security configuration for both incoming and outgoing calls is defined within the Security menu of the WAN set-up section.

ÄSecurity Level

The security level defines the type of security that this router will request when a remote site PPP router attempts to establish a PPP connection. The security may defined as none, PAP, or CHAP.

When a security level is defined on this router, an entry for each remote site PPP router that may be connected to this router must be placed in the security database. The security database is used to store the user names and passwords of the remote site PPP routers.

LR5200A-R2, LR5100A-T specifications

The Black Box LR5100A-T and LR5200A-R2 are advanced network media converters designed to facilitate seamless data transmission across various media types. These devices are particularly valuable for organizations seeking high-performance solutions for extending network communications beyond traditional limits.

The LR5100A-T is an Ethernet media converter that operates over twisted pair cabling, efficiently converting 10/100/1000 Mbps Ethernet signals into fiber optic signals. This capability allows businesses to harness the long-distance advantages of fiber optics while maintaining compatibility with existing Ethernet infrastructure. With a broad range of supported distances, users can effectively communicate over distances up to 100 kilometers, depending on the type of fiber optic cable used and the transmission rate.

In contrast, the LR5200A-R2 emphasizes compatibility with a wider range of fiber types and supports both multimode and single-mode fiber connections. It also provides auto-negotiation capabilities, which enable it to automatically detect and configure to the optimal speed of connected devices, streamlining setup and enhancing user experience.

One of the key features of both the LR5100A-T and LR5200A-R2 is their rugged design, making them suitable for deployment in harsh environments. They are engineered to withstand extreme temperatures and are resistant to vibration, ensuring reliability in challenging settings. Additionally, both models adhere to industry standards, ensuring interoperability with a diverse array of networking equipment.

Notably, these converters come equipped with LED indicators that allow for real-time monitoring of device status, simplifying network management and troubleshooting. This feature ensures that technicians are promptly alerted to any connectivity issues, significantly reducing downtime.

Powering options for both models include standard AC power supplies or Power over Ethernet (PoE), allowing for flexible deployment scenarios without the need for additional power outlets. This flexibility can be a crucial factor in environments where power availability may be limited.

With their blend of performance, durability, and advanced features, the Black Box LR5100A-T and LR5200A-R2 media converters represent a solid choice for organizations looking to future-proof their network infrastructure while ensuring high levels of connectivity and reliability. Whether extending existing networks or implementing new solutions, these devices provide the necessary tools for effective communication in today’s digital world.
