[dpdk-users] pfsense ipsec traffic decryption

[avatli]

Hello

Briefly, a host connects to a pfsense gateway and the traffic from
the host is encrypted with IPSec Tunnel mode, so I just need to know
how to decrypt the ESP traffic using DPDK. Is it possible?

If it makes any sense, I copied the pfsense configuration below
