[DSL] Netgear 7550 Hairpinning?I just received a new Netgear 7550 modem/router to go with my DSL speed upgrade. I got all my port forwarding and dynDNS updates working, but I cannot seem to connect to the dynDNS domain name from inside the LAN, nor can I ping the WAN interface via the dnyDNS domain name.
This is called "hairpinning", and I have been able to do this with every other router I have had. Essentially, the router needs to be able to route to its own public IP. Am I just not using it right? |

Maybe this will have some information of benefit to you. » seansite.dyndns.org/fron ··· nt/7550/ |

Are you sure you have the external ip address?
I noticed that during the first month I got a new ip address almost daily, lately it is has been stable and only changing every month or every other month. |

Thank you. The information is helpful, but it does not answer the hairpinning question. |

My dynDNS client gets the external address from the router and updates dynDNS regularly -- that part is working. I can contact my little server from work. But I can't from inside the LAN using the WAN address.
This is a problem because now I need separate scripts and shortcuts on my laptop for "inside" and "outside" the LAN; i.e., "work" and "home". It isn't insurmountable, but it is annoying and time-wasting. |

Just for nuts try going through a proxy for your laptop Opera browser does this by default. |

There are routers that support "hairpinning" aka loopback and there are routers that do not support hairpinning. The 7550 does not support hairpinning. |

said by wayjac:There are routers that support "hairpinning" aka loopback and there are routers that do not support hairpinning. The 7550 does not support hairpinning. You say that with such conviction, I almost hesitate to ask: do you know for certain if there is absolutely no advanced configuration that could be set, for example adding a rule to the routing table to accomplish this? |
