airvpn push ipv6 on ipv4 only connection floods log

willowvpn

openvpn 2.6.14, remote random, router

I removed

push-peer-info
setenv UV_IPV6 yes

I added "4" to tcp, which log confirms

proto tcp4

airvpn keeps trying to push ipv6, but since router is strict ipv4 only

Linux can't add IPv6 to interface tun0
Exiting due to fatal error

this keeps going a few hundred times, random servers, until suddenly some server (seems variable) no longer tries to push ipv6 and connection gets established.

I tried also, to no avail

pull-filter ignore "ifconfig-ipv6"
pull-filter ignore "route-ipv6"

setenv UV_IPV6=no

setenv UV_IPV6 no

Which ovpn file or other setting would get rid of airvpn pushing ipv6?

Please add or change the directive verb 4, then post the complete log of such a failed connection attempt.

Somehow --verb 4 was not applied, it's still verbosity level 3. I would've expected a complete listing of all OpenVPN directives first, to see what OpenVPN actually applied. But no matter, I'm seeing that you didn't filter out redirect-gateway ipv6 and tun-ipv6.
But what's more alarming, OpenVPN does not print out that it actually ignored those pushed options. Somehow I doubt your manual changes in the config are applied at all, so can you please check on that first?

You got me confused :doh:

Thanks for sticking with me on this.
Let's take one step at a time.
verb 4 I though meant remove "4" in proto tcp4. Where do I put this verb 4?

I have been having issues with AirVPN continually forcing IPv6 when I've done everything to disable and block IPv6 from my network.

Hello!

Please follow this message to quickly resolve the issue:
https://airvpn.org/forums/topic/26548-linux-ip-6-addr-add-failed/?do=findComment&comment=72069

The OP problem might be different so your case should not be discussed here.

Kind regards

I included the suggested

pull-filter ignore "dhcp-option DNS6"
pull-filter ignore "tun-ipv6"
pull-filter ignore "ifconfig-ipv6"

and getting errors:

@willowvpn

Hello!

Please try:

pull-filter ignore "ifconfig-ipv6"
pull-filter ignore "route-ipv6"
pull-filter ignore "redirect-gateway ipv6"
pull-filter ignore "dhcp-option DNS6"
pull-filter ignore "tun-ipv6"

Fixed the linked message as well (it was incomplete). If the problem persists send the whole log, do not cut it.

Kind regards

With those settings there are no more errors, tunnel establishes and is up and running, but now nothing is sent through the tunnel (tun). Not incoming, not outgoing. Log with the settings:
