23.1.2 works better,
but 1 or 2 times a day there is a ipv4 cut (ipv6 runs).

ipv4 lease on Deutsche Glasfaser is 1 hour.

(I´ve a linux skript wich tests every 5 seconds ipv4 and ipv6 connection).

Code: [Select]

Re: Default ipv4 route drop when WAN dhcp renew
« Reply #65 on: March 09, 2023, 11:28:59 am »
Yep, this is an ISP-related disruption with overly-aggressive lease time:

2023-03-09T03:45:26   Notice   opnsense   /usr/local/etc/rc.newwanip: IP renewal starting (new: 100.111.133.83, old: 100.111.133.83, interface: wan[opt4], device: vtnet0, force: yes)

There is room for improvement from our end but very likely not in the next 3 months.

Ok, thanks for reply.
How can I solve it?
Should I connect a FritzBox to ISP and then OPNSense to FritzBox?
FritzBox to ISP should work?!

Oh, thanks..

OPNSense as exposed Host?
No problems/ latency with double NAT in ipv4??

I don't use exposed host, but it depends on requirements. No latency but not a lot of traffic as per requirement either.

OK,now I put my FritzBox to ISP-Modem, and on FritzBox OPNSense.
This works, but 2 questions:

1. in my log is every few seconds:

2. I request a /56 Prefix-length for FritzBox and on OPNSense I request /60 prefix.
All works fine, BUT when I change something on FritzBox, so its restarting internet, ipv6-connection on OPNSense got lost (ipv6 seems to be there, but no traffic is possible).
When I restart OPNSense, it works fine...

I think it could be a prefix change issue.
When GritzBox get a new prefix und send it to Opnsense, it doesn‘t handle it good…

How can I fix it??
