OVPN IP address bug

Sat Jul 29, 2017 5:52 am

Hi,

Here is the story about this bug.

I'm running OSPF on OVPN.
The log showing a lot info.

The netmask mismatch.
It is very weird. Because the IP address was provide by OVPN server.

I go to check the both IP address on OVPN server and local router.

As you see, the local router has /24 netmask, but the server has /32 netmask.
This cause OSPF issue.

I also check L2TP and PPTP, they using same profile from OVPN.
The remote router and local router all are /32 netmask IP addresses.

Is it anyway to fix this?

Change OVPN server settings to use /32 netmask

Thanks, it works for me.

But i found the bug on 6.40.

Even the netmask has issues, OSPF works on previously version. But on 6.40, the routes list has problem to synchronization. All routes gate way will change to 0.0.0.0.
I have to downgrade from 6.40 to 6.38.
