Does any vendor make ethernet bridges that are solid state and about the size of a cigarette pack? Ideally I would like to find a vendor that offers these as plug in modules into a single rack mounted frame, so I could get a lot of them in a tight space. I want to use one of these in front of each segment on a 12 segment firewall, to filter any source IPs on the segment or filter by Mac address. The spoof detection on my firewall is harder to use than it should be and introduces reliability issues I don't want to deal with. I know that Allied Telesyn, Canary, and others make small copper to fibre converters that are small and fit into rackmountable enclosures. I am hoping that maybe one of them had the foresight to add in some ethernet bridging capabilities to those. -- Will | |||||||||||||||||||

I know there are some with multiple ethernet jacks and they are frequently used as routers. Linux is Linux. You can make it a filtering bridge if you want. SysAdmin magazine always has adverts for this stuff. Maybe you can find the vendors on the website. http://www.samag.com/ -- a d y k e s @ p a n i x . c o m Harrison for Congress in NY 13CD www.harrison06.com Don't blame me. I voted for Gore.

To get the manageability you want you will have to spend a bit but it will be less that some of the alternatives. I know that for example a Cisco Catalyst 2950 would do. Google - [two port ethernet switch] As far as I can see following are all Copper-Fiber convertors and may not be suitable for you. You need to have a look yourself though since I just had a glance. Allied Telesyn AT FS201 2-Port Ethernet Switch (AT-FS201-20) http://www2.shopping.com/xPO-Allied_Telesyn_AT_FS201_AT_FS201_20 It's made as a 10/100 convertor. Perfect if 10 is OK but it looks like they do GBE ones too. today announced the AT-WLMT wall-mount bracket set for its MC- and FS- series of standalone and bridging media converters. The AT-WLMT brackets are particularly useful in locations where a single media converter needs to be physically anchored. Available in packs of 10, the AT-WLMT includes all necessary fitting components to ensure trouble-free and fast installation. The AT-WLMT can be used for all of the Allied Telesis bridging media converter series (AT-FSxxx & AT-GS2xxx for Fast Ethernet and Gigabit). http://www.alliedtelesyn.co.uk/en-gb/products/cat/?cid=8 Google - [three port ethernet switch] Google - [five port ethernet switch] - These are cheap and common but most not managable. Try [four port too] http://www.engineeringtalk.com/news/kor/kor114.html | |||||||||||||||||||

Please log in for more thread options Alternately, there is a feature sometimes called PVE (Private Virtual Edge). Supported on some Cisco and Linksys devices amongst others. Doesn't inherently give you the advanced filtering desired, but should be more secure (in theory) than using VLANs. | |||||||||||||||||||
