Não é possível conectar ao endereço IP local OSX (Mavericks)

Question

Aqui está a situação:

• Eu posso pingar e conectar-me ao localhost / 127.0.0.1
• posso resolver hostname (dig / nslookup)
• Eu posso pingar meu endereço IP local (10.63.66.185) e nome de host de outra máquina
• Eu posso me conectar a um serviço em execução na minha máquina local de outra máquina (nc -l 12345)
• Não consigo pingar / conectar-me ao meu endereço IP local (10.63.66.185 - > 10.63.66.185)
• O firewall do OSX está desativado e nenhum outro produto de segurança está sendo executado
• A tabela de roteamento parece bem (lo0 existe e 10.63.66.185 - > lo0)
• Ele persiste mesmo depois de uma reinicialização

Portanto, estou perplexo sobre o motivo pelo qual não consigo me conectar ao meu próprio ip. Alguém tem alguma ideia ou precisa de mais informações? Aqui está a tabela de roteamento:
