OPNsense Forum

Hello,

i already posted in the 17.1 beta thread but it seems that i have a very special ISP configuration and reinstalled 16.7 latest to avoid beta problems.

Provider is wilhelm.tel/willy.tel

My scenario

• ipv4 over pppoe works very well
• my provider only supports a locallink address for IPv6 routing
• i need DHCPv6 Rapid Commit (any idea what that is?)
• i can ping the ISP ipv6 gateway from the router
• i do not get a prefix (afaik) and my lan interface does not announce a ipv6 prefix
• opnsense needs to use a ip address from the assigned prefix
• opnsense must ask for a prefix

My current WAN config (yes/no means i tried both)
IPv4 Configuration Type   PPPoE
IPv6 Configuration Type   DHCPv6
Enable debug yes
Use IPv4 connectivity   yes/no
Request only a IPv6 prefix yes/no
Directly send SOLICIT yes/no
DHCPv6 Prefix Delegation size   56 
Send IPv6 prefix hint   yes/no

ping6 gateway

Any idea whats wrong with my setup?

In the meantime i have some questions:

Where can i "see" the "track interface" implementation to debug the mechanism?

How can i get more debug information of the PPPoE and DHCPv6 process ? Even with the debug flag activated it is pretty reticent ...

How can i manually reconnect the pppoe connection in the cli ?

Thank you!

Hi,

i have the same problem but with Deutsche Telekom as my ISP.
Do you have gathered any debug possibilities so far you could share, or maybe you have fixed your problem already and have a clue what went wrong in the first place?
