[Resolvido] failover no pfsense em filiais
-
Quando tiro o cabo de um dos links eu não consigo que a filial comunique com a matriz. Só funciona se eu mudar a rota de ambos.
Acertou as regras na lan? definiu gateways na interfaces wan/metrolan? marcou a opção allow default gateway switch?
-
Talvez o que você precisa para esse cenário é usar OSPF, pode ser implementado pelo o openospf:
http://en.wikipedia.org/wiki/Open_Shortest_Path_First
http://pt.wikipedia.org/wiki/Open_Shortest_Path_FirstO pfsense oferece um package para isso.
Boa sorte !
-
Segue imagem de como é
quem fornece os links é vivo. esses links não possuem ip. Eu defino no pfsense o ip a ser utilizado. é como se fosse um "cabo" ligando a filial com a matriz. O que eu preciso fazer é que se um dos links cair, o outro assuma e não perca a conexão com a filial.
já fiz as regras de lan/metrolan e gateways e marquei a opção de gateway switch
-
a solução é OSPF como o Luiz Gustavo falou. vc tem um loop na sua estrutura..
-
tenho q instalar o ospf na filial tb?
-
-
instalei mas ainda não deu certo
-
Configuração, certeza.

montei um ambiente simulando o que preciso fazer aqui com uns servers antigos

resolvi aqui. era só tirar as rotas em system static routes
-
Coloque como resolvido.. vc usou o ospf mesmo ??
-
sim.
usei o ospf mesmo
