Finally, i resolved my problem.
I downloaded the repository to a computer, later i install an apache server and put inside the repositoty.
With Winscp yo must connect to pfsense server and modify the file: pfsense-Repo.conf in /usr/local/share/pfSense and /usr/local/share/pfSense/pkg/repos . Change https by http and put in tha line your apache site ip
FreeBSD: { enabled: no }
pfSense-core: {
url: "pkg+http://YOUR APACHE IP/pfSense_v2_3_4_amd64-core",
mirror_type: "srv",
signature_type: "fingerprints",
fingerprints: "/usr/local/share/pfSense/keys/pkg",
enabled: yes
}
pfSense: {
url: "pkg+http://YOUR APACHE IP/pfSense_v2_3_4_amd64-pfSense_v2_3_4",
