Não é possível conectar-se ao umurmur na porta 64738 com o firewall ativado

Question

Estou usando µMurmur no OpenWRT, que tem a seguinte configuração:

umurmur.conf:

max_bandwidth = 130000;

# bindport = 64738;
# bindaddr = "192.168.1.1";

# Log to file option. Default is logging to syslog.
# umurmurd will close and reopen the logfile if SIGHUP is received.
logfile = "/var/log/umurmurd.log";

#imagemessagelength = 131072
#allowhtml = true

Que, de acordo com configuração de umurmur , significa que:

bindaddr (INADDR_ANY = all addresses the host is assigned)
bindport (64738)

O servidor é vinculado a cada IP que o dispositivo possui.

Esta é a configuração do meu firewall:

O servidor está acessível por 192.168.1.1:64738 , mas não por IP externo. No entanto, se eu desligar o firewall, o servidor ficará imediatamente disponível.

Eu não sei como resolver mais problemas e qualquer ajuda é apreciada.
