General Discussion / IPv6 Setup wont work with Proxmox also Unbound 100% after setting up IPv6 on WAN

« on: September 16, 2023, 02:10:16 pm »

Hey guys, ive been trieng to setup IPV6 on my Proxmox Node and also put it into my OPNSense so i can give my VMS in the Lan Network IPV6 connectivity. Ive been trieng around but i cant get it to work my OPNSense VM cant seem to ping the Gateway i have tried around alot and cant get it working here are my settings maybe somebody of you guys has a ide: (X are there to hide my ipv6 ^^)

IPV6 Subnet of my ISP
2a05:XXXX:1:17::/64    GW 2a05:XXXX:1:17::1/64

proxmox settingsvmbr0
vmbr0 nutzt eno3
2a05:XXXX:1:17::50/64
GW: 2a05:XXXX:1:17::1

opnsense vm:
wan (vtnet0) (its the vmbr0 in proxmox)
interface settings:
static ipv6: 2a05:XXXX:1:17::100/64
GW: 2a05:XXXX:1:17::1

opnsense also has the 2a05:XXXX:1:17::1 as a default gateway "netstat -rn -f inet6"

Proxmox Config: /etc/network/interfaces:
auto lo
iface lo inet loopback

iface eno1 inet manual

iface eno2 inet manual

auto eno3
iface eno3 inet manual
        post-up echo 1 > /proc/sys/net/ipv4/ip_forward
        post-up echo 1 > /proc/sys/net/ipv4/conf/eno3/proxy_arp

iface eno4 inet manual

auto vmbr0
iface vmbr0 inet static
        address 109.230.XXXX.38/28
        gateway 109.230.XXXX.33
        bridge-ports eno3
        bridge-stp off
        bridge-fd 0

iface vmbr0 inet6 static
        address 2a05:XXXX:1:17::50/64
        gateway 2a05:XXXX:1:17::1

auto vmbr1
iface vmbr1 inet static
        address 10.10.0.0/24
        bridge-ports eno2
        bridge-stp off
        bridge-fd 0
#SwitchNetwork 10.10.0.x/24

auto vmbr2
iface vmbr2 inet static
        address 192.168.178.200/24
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0


Also when setting up the WAN Interface my Unbound Service starts taking up 100% CPU for some reason.
Why could that be?
