ASF GitHub Bot commented on CLOUDSTACK-10043:
---------------------------------------------
resmo opened a new pull request #2323: CLOUDSTACK-10043: fix restore default
drop for egress rules in ACL
URL: https://github.com/apache/cloudstack/pull/2323
While verifying the fix for CLOUDSTACK-10135 in #2313 we found a regression.
At least to version 4.5.x (verified in 4.5.3) every ACL hat a default drop
for egress (ACL_OUTBOUND). This commit restores this behavior (regression fix)

> Egress Rule in VPC ACL broken
> ------------------------------
>
> Key: CLOUDSTACK-10043
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10043
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Virtual Router, VPC, XenServer
> Affects Versions: 4.9.2.0
> Environment: Cloudstack 4.9.2.0
> XenServer 6.5SP1
> Zone with Advanced Network
> Reporter: Francois Scheurer
> Assignee: René Moser
> Priority: Blocker
>
> The Network Offering of the VPC Tier has a Default Egress Policy = Deny.
> Some Allow Rules exist in the ACL, but _ALL_ egress connections are possible.
> Creating a Deny All rule explicit at the end of the rules is actually
> blocking ALL traffic (should not, because of the Allow rules).
> The Iptables in the VR are wrong:
> 1) the allow & deny rules are in wrong order.
> 2) some rules are in mangle table instead of filter
> Do you know how to fix this?
> Thank you for your help.
> Francois Scheurer
