Hello everyone, I'm currently trying to move my OpenVPN users from TAP devices to TUN devices because Apple states that they will disable TAP in the near future. I have it working for IPv4 just fine, but IPv6 gives me a little OSPF6 issue. The tun0 interface has the following state, even when people are connected: tun0 is up, type POINTOPOINT   Interface ID: 42   Internet Address:     inet : 172.31.8.1/32     inet6: 2a02:b70:0:2::1/64   Instance ID 0, Interface MTU 1500 (autodetect: 1500)   MTU mismatch detection: disabled   Area ID 0.0.0.0, Cost 10   State Down, Transmit Delay 1 sec, Priority 1   Timer intervals configured:    Hello 10, Dead 40, Retransmit 5   DR: 0.0.0.0 BDR: 0.0.0.0   Number of I/F scoped LSAs is 0     0 Pending LSAs for LSUpdate in Time 00:00:00 [thread off]     0 Pending LSAs for LSAck in Time 00:00:00 [thread off] I think the "State Down" is the root cause for the routes to this interface not showing up on other routers, which results in IPv6 traffic failing completely. Could someone tell me if this is intentionally, or that I have some potential config error? If I need to share my whole configuration, let me know, my hope is that it is something simple related to TUN interfaces / POINTTOPOINT interfaces. interface tun0  ipv6 address 2a02:b70:0:2::1/64  ipv6 nd suppress-ra  ipv6 ospf6 mtu-ignore  ipv6 ospf6 network point-to-point  no link-detect router ospf6  interface tun0 area 0.0.0.0 ipv6 route 2a02:b70:0:2::/64 tun0 -- Kind regards Jan Hugo Prins /DevOps Engineer/ <https://betterbe.com> Auke Vleerstraat 140 E 7547 AN Enschede CC no. 08097527 <https://www.kvk.nl/orderstraat/product-kiezen/?kvknummer=080975270000> *T* +31 (0) 53 48 00 694 <tel:+31534800694> *E* jprins@betterbe.com <mailto:jprins@betterbe.com> *M* +31 (0)6 263 58 951 <tel:+31 (0)6 263 58 951> www.betterbe.com <https://www.betterbe.com> BetterBe accepts no liability for the content of this email, or for the consequences of any actions taken on the basis of the information provided, unless that information is subsequently confirmed in writing.
