Description Paul Moore 2008-11-14 18:40:25 UTC
Description of problem:
The default IPv4 and IPv6 firewall rules do not allow inbound IKE traffic and the bundled firewall configuration tools do not allow administrators to enable IKE traffic.  This has caused problems when trying to establish IPsec connections over IPv6 using IKE.

The problem was solved by adding the following line to /etc/sysconfig/ip[6]tables and restarting the firewall services.

 -A RH-Firewall-1-INPUT -p udp --sport 500 --dport 500 -j ACCEPT

Version-Release number of selected component (if applicable):
iptables-1.3.5-4.el5
iptables-ipv6-1.3.5-4.el5

How reproducible:
Everytime

Steps to Reproduce:
1. service ip6tables start
2. try to initiate an IKE negotiation over IPv6
  
Actual results:
IKE negotiation will fail due to a phase-1 timeout caused by a lack of communication with the remote host.

Expected results:
IKE negotiation succeeds.

Comment 1 Steve Grubb 2008-11-15 13:45:54 UTC
Paul, are you saying that we should add IKE/IKE2 to system-config-firewall IPSec settings? We have a tight set of default rules and should allow for easy changes by system-config-firewall.

Comment 2 Paul Moore 2008-11-17 14:17:43 UTC
Honestly I really don't care how you solve the problem, but as it stands right now with RHEL5.2 the only way to enable IKE negotiations is to either manipulate the configuration files directly or disable the firewall.  Neither approach seems like a good solution to me.

Comment 3 Subhendu Ghosh 2009-03-25 16:17:51 UTC
Moving this to system-config-securitylevel for addition of options to allow incoming IKE negotiations.
