pppoe using chelsio T520

[stefhen]

Hi,

I am using a Chelsio T520-CR 2x SFP+ 10G NIC and I am unable to make PPPoE working using one of this card interface.
Using another card like the Intel 1000 there is no issue with exactly the same configuration.
My operating system is FreeBSD 13.1-RELEASE-p3 / OPNsense 22.7.8-amd64

Using the Chelsio NIC the pppoe authentication is made without issue, I'm getting a public address from BELL, I can even ping any public address from the LAN side of my network (icmp traffic is working fine), but I am unable to access a web site or other internet protocols (http, https, ssh etc...)

I've found a thread talking about the same problem but it's quite old:
»forum.netgate.com/topic/ ··· nterface

I would like to know if someone tried pppoe using this card recently?

Thanks

I found the solution in another forum:

Add "hw.cxgbe.buffer_packing=0" to /boot/loader.conf.local

to fix this issue if you have the same problem.
