ipv6

Recently I have started to DualStack my online services and wondered how many of us actually started/completed the conversion? Please share your experience/issues and future plans too..

Hopefully my experience and analysis will be appreciated here. IPv6 was developed having multihoming in mind, and it can be beneficial when no single “good” IPv6 supply exists locally. In many parts of the world an ISP can linger in business without offering IPv6 connectivity. The shortage of...

Has support for dual stack IPv4/IPv6 changed with RELEASE-13.0? I have a daemon running on a VPS on which net.inet6.ip6.v6only=0 is set in /etc/sysctl.conf. When the VPS was running 12.2, netstat -a would show a "tcp46" listen protocol and connections over both v4 and v6 worked fine. After...

Hi, I have a IPv6 address block of prefix size 64. On my host computer running FreeBSD 13-RELEASE I have three jails: jls JID IP Address Hostname Path 1 svcfw /usr/jail/svcfw 2 www...

Hello! Seems that an expert help is needed here. My network provider supports IPv6. Also, I have installed net/dual-dhclient In the /etc/rc.conf I have: ipv6_activate_all_interfaces="YES" dhclient_program="/usr/local/sbin/dual-dhclient" ifconfig_bge0="DHCP accept_rtadv" After running...

Hi, I have enabled router advertisements on my FreeBSD 13.0 amd64 machine, but I am not getting a global IPv6 address. My rc.conf looks like the following: ifconfig_DEFAULT="SYNCDHCP mtu 1460 accept_rtadv" ipv6_activate_all_interfaces="YES" I am receiving router advertisements on a Linux...

Is it possible to complete disable IPv6? I've tried on /etc/rc.conf: ... and it seems that it is still active.

Hi all, I have an OpenBSD router that sends out router advertisements on the main network, my FreeBSD machine gets a public IPv6 as it's supposed to get. Now I've set up a VLAN on both machines for a VPN transfer net. When I tested that with manually set addresses, it worked as expected. Now I...

Hi. I run an IPv6-enabled FreeBSD router on my home network, which has been working fine for years. I have a global-scope /48 prefix delegated by my ISP, from which FreeBSD advertises a /64 chunk to my LAN. IPv6-enabled hosts on the LAN see the router advertisements and configure themselves...

Hi, I have a box acting as a gateway for my lan at home. It connects through PPPoE (tun0) to the provider and gets the configuration for the outside world (I'm using net/dhcpcd). The clients (on the lan) are served by rtadvd and net/dhcpd. I have a 192.168.1.0/24 network for LAN and also want...

I'm running an AP that bridges traffic to my ISP. For various reasons, I'm running both IPv4 and IPv6 and I need to NAT traffic from the LAN to the ISP. For this reason, net.inet6.ip6.forwarding needs to be enabled. The usual solution for periodically updating the IPv6 gateway address seems to...

Hi This problem originated from my pfSense installation, but I just confirmed that I'm having the same problem with a clean installation of FreeBSD 12.2, so I thought I would ask here. The problem is that FreeBSD does not answer NS send from my ISP's router, which results in no communication...

I am seeking help here as despite reading the documentation for rc.conf I am clearly missing something. I wish vtnet0 to be disabled on boot along with ipv6 being disabled on vtnet1. I am perhaps being lead astray from the output so forgive me, I am a new user to BSD. rc.conf...

Hi there, I have a FreeBSD 12.1 server, which has 2 network interfaces: re0: the only physical ethernet interface, connecting with the internal devices tun0: the external interface, to be assigned IPv6 prefix by ISP via PPPoE And here's the configuration snippet for them: # /etc/rc.conf...

I could mange to install Windows Server 2019 on FreeBSD 12.1-R + Bhyve by following https://wiki.freebsd.org/bhyve/Windows, etc but am having problems with TCP/IPv6 connections as follows: * All firewalls are turned off on both host FreeBSD and guest Windows. * The guest Windows is assigned to...

What is the proper way to enable FreeBSD to listen on lets say 4000 IPv6? Adding 4000 them at rc.conf as ifconfig_igb0_aliasXXXX=... " just hangs my server after /etc/netstart All ip's are from 1 subnet but they are not sequential .

Hi all, Since 2018 I have a FreeBSD server acting as a WireGuard "server". This server has an IPv6 tunnel, courtesy of Hurricane Electric (https://tunnelbroker.net) and I have successfully distributed those IPv6 addresses to the VPN peers, so they now live in the future. Every single one of...

Port net-mgmt/netbox is a nice tool widely used for IPAM and DECIM maintenance, so I tried to use it for maintenance purposes at work. I never got past the setup, since the example shown in FreeBSD's wiki (https://wiki.freebsd.org/Ports/net-mgmt/netbox) only covers a setup as vhost, which...
