Well, not a perfect solution, but definitely one that should work - with ipsec performing as Tzafrir described, and using the the mangling table as Alex has Looks like I'm gonna kill my uptime to try and do this. Wish me luck :-) ---= Miki Shapiro =-- ---= Cell: (+972)-56-32

Hi, I recommend you read the IETF's comprehensive list of papers in: http://www.ietf.org/ids.by.wg/ipsec.html maybe you will find there your answer and read the RFCs and surely you will find the answer. At 17:33 20/05/01 +0300, you wrote: >Are we *absolutely sure* we're not confusing >(1) IP-lay
