You can try adding your ftelnet proxy IP to the Whitelist= line in your
net2bbs.ini file.

For example if you're using proxy-us-nj.ftelnet.ca as your proxy try adding

Whitelist=162.253.176.32


From https://pcmicro.com/NetFoss/guide/net2bbs.html:

WhiteList=    List of up to 4 IP Addresses which will always be
              accepted, bypassing the AntiHammer, AntiPortScanner,
              and Maximum Same-IP connections checkers. They are
              comma delimited. Hostnames and wildcards are not allowed.
