From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.9 (X11; Linux i686; U;) Gecko/20030314 Description of problem: If you route through a pair of Redhat 8 boxes that have a cipe tunnel between them, and use iptables to masquerade the SA(source address) on the remote router tcp sessions will hang. Version-Release number of selected component (if applicable): cipe-1.4.5-11 How reproducible: Always Steps to Reproduce: 1. Establish cipe tunnel between two gateways 2. Masquerade SA on remote routes 3. Do any high packet rate tcp session Actual Results: TCP session hangs Expected Results: TCP session does not hang Additional info: http://sites.inka.de/bigred/archive/cipe-l/2002-02/msg00026.html This is seriously broken, should be enough justification to go to 1.5.4. The backwards compatability issues are not an issue according to posts I have seen from Olaf on the upgrade cipe bug. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=68066
Since you guys don't include cipe in any newer releases this is fruitless.
