Hola gente, quedó SOLUCIONADO, era el ufw, no tenía idea que estaba
instalado en ese equipo. Pero lo cierto es que comenzó a actuar a partir
de la actualización a bullseye, con buster no bloqueaba nada. Es muy raro.
Gracias a OddieX por la ayuda y a todos los que respondieron, aprendí
unas cuantas cosas para chequear que nunca había tenido que usar.
La solución: descubrí que había una interfaz gráfica para el ufw en el
equipo en cuestión, ni bien la abrí vi que estaba todo denegado, así que
cambié las opciones y ahora puedo ingresar.
La verdad que no recuerdo haber instalado ese firewall ni haberlo
configurado nunca. Espero que no sean los años... ;-)

Saludos a todos y gracias nuevamente.

Con Putty tampoco se conecta al equipo en cuestión, a los demás no hay
problemas.

Fijate en login.Defs q no encuentra iptables pq desde buster en
adelante cambiaron los env path... Sino whereis iptables y ejecutalo
con path completo...
Funcionó indicando la ruta completa, aquí va la salida, yo no veo
inconvenientes, pero no estoy muy ducho con estos (disculpas porque es
bastante larga)...

Evidentemente tenes el ufw configurado, y tenes todo bloqueado...
Fijate baja el ufw y proba... Tambvien investiga como abrir esos puertos!
