bom dia Denis

os clientes wireless usam uma antena nanostation (trabalhando em modo
bridge) pra se conectar, quando olho a tabela arp mostra os ips das
máquinas porém com o MAC da nanostation, sempre foi assim...

o servidor tem duas placas mas uma sai pra rede externa wireless e a outra
vem pra rede interna pra chegar no gateway principal.

o que me intriga é essa mensagem com um IP nada a ver: *Mar  7 11:32:37
valinor kernel: arplookup 169.254.11.248 failed: host is not on local
network*
