Cisco 857 - Hairpinning

kyle · ‎07-16-2008

How would I go about enabling hairpin routing?

I need the Cisco to take a packet from an internal device that's destined for the Di0 IP to be forwarded back internally according to the existing port forwarding rules.

No-one seems to know how, surely there's a guru out there that knows how to get it done!

I gave up, pulled the bloody Cisco out and put in an bridging modem, with an embedded solution behind it doing IPTABLES and PPPoE.

Problem solved.

Get your act together Cisco! That's 2 things I've found that the 800 series cannot do.

- Port forwarding ranges

- Hairpinning
