I have two tenants currently sharing the same patch panel. They were sharing same ISP, until yesterday. Now they have the same ISP, but two different ISP communications box (ADTRAN 600, for voice and data). I want to keep both tenants on the same patch panel, but split them to their own switch and ADTRAN. IT would have been easy if there were two patch panels for each office. I noticed that both ADTRAN have the same local ip scheme of 172.17.2.0 - 172.17.2.254, they even have the same exclusions. The same company is providing service, so I guess they were unaware that both clients share the same patch panel, hence they were both issued the IPS's default scheme. There is am SBS server in DHCP and DNS mode, I want to keep it like that. I think I need to have the ISP change the local ip scheme on one of the ADTRAN, because even with each client on his own switch (sharing patch panel of course), I am unable to get internet access on one client. What options do I have? Can having the ISP change the scheme on the ADTRAN solve the issue?<br />

I have two tenants currently sharing the same patch panel. They were sharing same ISP, until yesterday. Now they have the same ISP, but two different ISP communications box (ADTRAN 600, for voice and data). I want to keep both tenants on the same patch panel, but split them to their own switch and ADTRAN. IT would have been easy if there were two patch panels for each office. I noticed that both ADTRAN have the same local ip scheme of 172.17.2.0 - 172.17.2.254, they even have the same exclusions. The same company is providing service, so I guess they were unaware that both clients share the same patch panel, hence they were both issued the IPS's default scheme. There is am SBS server in DHCP and DNS mode, I want to keep it like that. I think I need to have the ISP change the local ip scheme on one of the ADTRAN, because even with each client on his own switch (sharing patch panel of course), I am unable to get internet access on one client. What options do I have? Can having the ISP change the scheme on the ADTRAN solve the issue?

How to share same patch panel with two different ISP

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Routers

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
