"inet6 eui64" is if you just want link level address (i am advised!) so whatever works for you, fine, but it is not that umb is a special case. having said that, we're discussing whether the page warrants an example config or not... glad you got it working though, and great you managed to dig through commit logs to find answers! jmc

Can you confirm that after you enabled IPv6 as per your second email that you can see one? The link-local address shows as soon as I enter # ifconfig umb0 inet6 eui64 Great because you will (always) need a link-local before you get any other type of IPv6 address. After successfull authentication, I also get my global IPv6 address. Good news. Can you check if your network support other mechanisms than eui64: temporary , soii ? 'ifconfig umb0 inet6 temporary' or 'ifconfig umb0 inet6 soii' Don't know if you can combine these options though.. -- Willy Manga

IPv6 with umb(4)
Moin! I tried unsuccessfully to obtain an IPv6 address with an umb(4) interface. As umb(4) supports IPv6 since 6.7, I seem to be doing something wrong. Can anyone give me a hint what I need to do? For testing purposes, I have already deactivated pf and tried to use dhcpcd. But I still had no success. I have attached my umb0 config and an excerpt from dmesg. If more information is needed for assistance, I will provide it later. --Huhn x270$ cat /etc/hostname.umb0 apn internet pin roaming up x270$ ifconfig umb0 umb0: flags=8851 mtu 1500 index 5 priority 6 llprio 3 roaming enabled registration home network state up cell-class LTE rssi -89dBm speed 47.7Mbps up 286Mbps down SIM initialized PIN valid (3 attempts left) subscriber-id ICC-id device EM7455 IMEI firmware SWI9X30C_02.24.03.00 phone# +49xxx APN internet provider Telekom.de provider-id 26201 dns 10.74.210.210 10.74.210.211 groups: egress status: active inet 10.72.239.216 --> 10.72.239.217 netmask 0xfff0 x270$ dmesg OpenBSD 7.5-current (GENERIC.MP) #19: Mon Apr 8 08:39:06 MDT 2024 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP [...] umb0 at uhub0 port 3 configuration 1 interface 12 "Sierra Wireless, Incorporated Sierra Wireless EM7455 Qualcomm Snapdragon X7 LTE-A" rev 2.00/0.06 addr 2 ugen0 at uhub0 port 3 configuration 1 "Sierra Wireless, Incorporated Sierra Wireless EM7455 Qualcomm Snapdragon X7 LTE-A" rev 2.00/0.06 addr 2 [...]
