ping sendto no buffer space available

[cryptoparty]

Hello !

I pinged gw from opnsense and saw :

Host is down.

Then I added entry to arp table with gw's interfaces.

After this one I see error : ping sendto no buffer space available



I don't know how to fix it. Please help me with that

[cryptoparty]

So  what do I need to tune?

There's a comprehensive troubleshooting guide from pfSense regarding this error:
https://doc.pfsense.org/index.php/No_buffer_space_available

I'll consider it to be a starting point for further analysis/debugging.
