Not found vpnc for el8 in EPEL

In the company where I work, some users use vpnc. Since version 8 the vpnc package has disappeared from EPEL.

Is there an alternative to using this vpn? Any way to install the package?

I readed: OpenConnect is a CSTP-only client and does not support IPsec for Cisco VPNs – neither the new IKEv2 variant, nor the traditional "Cisco IPSec".

Compiled but I have had problems with headers when running the binary.

Thank you.
