On CentOS 6?
Is the interface going up and down a lot?

The future appears to be RHEL or Debian. I think I'm going Debian.

How do you know it is losing that parameter?
I'm also guessing you have that parameter defined in /etc/sysctl.conf since you want to keep it persistent, yes?
Also, just poking around, it seems like that setting defaults to "0" already. When the issue occurs, what is that option getting set to?
Use to see.

Use
Code: Select all
sysctl -a | grep rp_filter
Re: [Losing parameter setting (net.ipv4.conf.ipsec0.rp_filter = 0)]
It would be normal for it to reset to the default if the interface is restarted. And that tends to happen quite often with VPNs...
