Mediacom has begun allocating IPs in 173.0.0.0/8 to its customers. At least one of your upstream routers has that source network blocked as known-bogus -- which it was until early this year, when IANA freed it up for use by Mediacom and other providers. Legitimate traffic can now originate from that network, but the routers in question are not getting dynamic updates to the bogon list. They are still stuck with a list that predates the Feb 2008 "legitimization" of that network. So they still block the traffic based on having an illegitimate source. The question is, as BC Web, do you maintain your own routing equipment all the way up the line to the Net at large -- or do you get your uplink from a datacenter or ISP, with a managed router? The answer will determine who has to fix the router(s). --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.imprimia.com/products/software/freeutils/SPAMC32/download/release/ Defuse Dictionary Attacks: Turn Exchange or IMail mailboxes into IMail Aliases! http://www.imprimia.com/products/software/freeutils/exchange2aliases/download/release/ http://www.imprimia.com/products/software/freeutils/ldap2aliases/download/release/ To Unsubscribe: http://imailserver.com/support/discussion_list/ List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://imailserver.com/support/kb.html
