General Discussion / "No route to host": need to reload WAN every ~24 hour
« on: February 01, 2023, 09:42:31 pm »
Configuration:
WAN is connected to internet through vlan832 of igb2.
IPs are received with DHCPv4 and DHCPv6 (/56 prefix delegation).
WAN:
LAN has a /24 IPv4 subnet, and a /64 IPv6 subnet (from the prefix).
LAN:
I do have multiple interfaces other than LAN for DMZ and users, but their configuration is very similar to LAN.
Issue
After having a working internet connection for a bit more than 24 hour, I lose all access to the internet.
A workaround would be to setup a crontab to reload the interface automatically every 24 hour, but It woundn't fix the issue itself.
The issue only occurs since I updated to 23.1.
Thank you

Issue
After having a working internet connection for a bit more than 24 hour, I lose all access to the internet.
- Internal networking between subnets works fine
- WAN interface still have its IPv4 and IPv6
- Some Wireguard tunnels keeps working, although the client is on the internet
- Pinging 1.1.1.1 from the firewall returns "ping: sendto: No route to host"
- Pinging from LAN returns a similar error
- Console shows IPv6 errors: "cannot forward src fe80:x:x:x:x:x:x:x, dst [some internet IPv6], nxt 17, rcvif lagg0_vlan50, outif igb2_vlan832"
- Web UI: clicking on "Reload" for the WAN interface DHCP (in the "overview" tab) fixes the issue instantly for ~24 hour
A workaround would be to setup a crontab to reload the interface automatically every 24 hour, but It woundn't fix the issue itself.
The issue only occurs since I updated to 23.1.
