Does your company use a firewall / router filter that filters the
packets sent to/from your Squid server?

Not unless you do a minimal change in the code. Squid first tries
passive connections, and if the server don't support PASV then old
"active" connections are used, but the code can easily be changed into
thinking that PASV is never supported.

change src/ftp.c:
    ftpState->flags.pasv_supported = 1;
    ftpState->flags.pasv_supported = 0;
