Minha culpa ou culpa do provedor

Question

Minha rede doméstica é a seguinte

Fiber to ethernet router from isp
HH Procurve 4000 managed switch
  VLAN: external
        Fiber router
        WAN side of belkin and netgear routers
  VLAN: LAN side of belkin and netgear routers
        All clients and server
belkin wireless router
   WAN: static ip x.x.x.212
        Mask 255.255.255.248
        Gateway x.x.x.209
   LAN: 192.168.7.1
Netgear wireless router
   WAN: static ip x.x.x.214
        Mask 255.255.255.248
        Gateway x.x.x.209
   LAN: 192.168.8.1
Server http,smtp,imap,pop3,ftp
   Static ip 192.168.7.202
          Mask 255.255.0.0
          Gw 192.168.7.1
   Static ip 192.168.8.202
          Mask 255.255.0.0
          Gw 192.168.8.1

Http,smtp,imap,pop3,ftp ports on belkin forwarded to same ports ip 192.168.7.1
Same ports on netgear routed to ports ip 192.168.8.1
Some clients gatway to 192.168.8.1 and some to 192.168.7.1

Então aqui está o problema Clientes usando o gateway 192.168.8.1 podem acessar o servidor via x.x.x.214 , mas não x.x.x.212 Clientes usando o gateway 192.168.7.1 podem acessar o servidor via x.x.x.212 , mas não x.x.x.214

É minha culpa ou culpa do meu provedor?
