Vyatta - Hub And Spoke - OSPF over GRE over IPSEC

So my planned more frequent updates to my blog did not exactly go to plan.

Oh well :) I'm posting today with a good one.

Today we are once again playing the role of a Managed Service Provider who is providing a Managed Cloud Service + Firewall the customer however has two Cisco 3745 routers.

We have two Hubs MSP-R1 and MSP-R2 both Vyatta and R1,R2 both IOS.


Here is a picture:

Vyatta to Cisco - Tunneling from ASA to Vyatta Using VMware and GNS

Its been a while since my last article/lab apologies for that, hopefully I will get back to my once a week schedule (fingers crossed)

So that lab today is for connecting a Vyatta router to a Cisco ASA/PIX and creating a Lan to Lan Tunnel with some one to one src/dst NAT thrown in for good measure :)

Here is the lab:




Here is the proof that is works:

Setting up a Vyatta Cluster with VRRP and IPSec Site to Site VPN

Well seeing as we have done this with the closed source alternative (PIX here)
It was time to do the decent thing and do an open source version...so here we go..

Diagram of the lab:




Basic setup of the lab:

Vyatta Cluster Part 1 - Basic Setup from Richard Vimeo on Vimeo.

Part two of the setup:

Vyatta Cluster Part 2 - Basic Setup from Richard Vimeo on Vimeo.

This is the juicy bit, where we setup VRRP, then Clustering and finally, IPsec site to site VPN. (There is some NAT in there too!:)

Vyatta Cluster Part 3 - VRRP, Clustering,VPN etc from Richard Vimeo on Vimeo.

This is where I try and break it!

Vyatta Cluster Part 3 - Testing from Richard Vimeo on Vimeo.

As ever enjoy! and let me know what you think :)
