¿Cómo obtengo solo la línea 443 y no la línea 4433? está ingresando ambos en la variable para verificar. Si hago la cadena manualmente, coloca la cadena a continuación en la variable.
10.0.0.30:443 10.0.0.30:4433
Aquí está mi resultado final repetidamente:
Added port forwarding for HTTPS
Nothing Altered for PrivateTTY
Nothing Altered for HTTP

En lugar de
grep ${mylanip}:443
hacer
grep "${mylanip}:443 "
entonces el espacio en blanco después de 443 forma parte de la expresión de búsqueda.
