[RESOLVIDO] Guarddog x Firestarter diferenças nos bloqueios

dupavesi · 27 de Novembro de 2008, 12:58

dae pessoal!!
estou c/ problema em dois servicos de rede.....amule e rede interna c/ firestarter e guarddog.....
vou explicar:
estou utilizando o kde atualmente, antes estava no gnome.....me conecto a internet via router c/ as devidas portas do amule abertas.....
pois bem, tenho os dois firewalls instalados aki, apesar de os dois serem interface grafica do iptables, ambos configurados p/ o acesso aos serviços do amule e da rede interna....
meu sistema está habilitado p/ inicializar automaticamente o firestarter, c/ ele eu consigo acessar o amule corretamente porem nao acesso a minha rede interna porém qndo eu paro ele e aplico as configuraçoes do guarddog eu acesso a rede mas o amule nao conecta......
p/ o firestarter eu achei uma dica aki: http://ubuntuforum-br.org/index.php/topic,1730.0.html q diz p/ desabilitar a opcao "Block broadcasts from external network" porem nao funcionou.....

peguei as configuraçoes do iptables d cada um dos "firewalls":

hj avancei um pouco qndo liberei o intervalo todo de ip's da rede nas portas de serviços do samba (137-139 445) assim consegui ver minhas pastas q estão compartilhadas.......
jah eh um avanço mas ainda nao consigo acessar o outros computadores.....

dupavesi · 29 de Novembro de 2008, 10:46

consegui resolver c/ o firestarter....
era soh colocar os ips das máquinas que vc quer ter acesso na area "permitir conexoes da maquina" e desmarcar o "Block broadcasts from external network" nas preferencias......
e nao precisa liberar as portas do samba.....
