We ran into problems with some implementations of dynamic NAT. The dynamic NAT kept a table of which internal address was attached to which connection of the single external address. Everything was cool as long as the number of connections were small. But as connections (of all types) increased the table filled. Then when a new connection was made, older connections were dropped unceremoniously. Dynamic NAT's of this sort are useful for things like surfing where connections are very ephemeral, but not persistent client/server connections. The solution? With this particular router, a static NAT, where each client that needed an individual external IP. That's the only way this router would lock an entry in the translation table. Other routers/firewals/proxy servers may have other methods -- but I didn't investigate further. -rje -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Robert Eskridge INET: [EMAIL PROTECTED] Fat City Network Services -- (858) 538-5051 FAX: (858) 538-5051 San Diego, California -- Public Internet access / Mailing Lists -------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
