Ping packet size on WAN

[pgard]

Is there a limit to ping packet size on WAN?
Enabled in firewall, but i get reply only with max. ping packet size set to 992 bytes. With bigger packet size i get time out.

No limit in pfSense. You may find limits in some modems, firewalls, routers and other network devices.

ping -4 -l 1460 google.com

Pinging google.com [74.125.139.138] with 1460 bytes of data:
Reply from 74.125.139.138: bytes=64 (sent 1460) time=40ms TTL=39

Thank you for answer.
But limit is only on pinging WAN interface from outside. 
When pinging from LAN to WAP IP or any other (google.com) get echo on any packet size.
