DynDNS and PPP interfaces
-
Ive got a 4g WAN failover line connected through a PPP interface, upon boot trying to update record via DynDNS I see these errors in my logs.
Time Process PID Message Jul 3 13:40:43 php-fpm 97750 /rc.dyndns.update: Dynamic DNS (****.***.org) There was an error trying to determine the public IP for interface - opt16 (ppp0 ). Jul 3 13:40:43 php-fpm 97750 /rc.dyndns.update: Dynamic DNS cloud flare (****.***.org): IP address could not be extracted from checkip.dyndns.orgIm updating a similar record at Cloudflare for my cable WAN which works fine so not sure what could be different.
Heres the interface status
WAN2 Interface (opt16, ppp0) Status up PPP up Uptime 00:30:57 MAC Address 00:00:00:00:00:00 IPv4 Address 10.124.156.xxx Subnet mask IPv4 255.255.255.255 Gateway IPv4 10.64.64.0 IPv6 Link Local fe80::207:43ff:xxxx:xxxx%ppp0 MTU 1492 In/out packets 1929/2024 (74 KiB/62 KiB) In/out packets (pass) 1929/2024 (74 KiB/62 KiB) In/out packets (block) 0/1 (0 B/72 B) In/out errors 0/0 Collisions 0Editing the DynDNS entry and forcing 'Save and Update' seems to be more productive, at least the text turns green indicating its been updated.
