Hi i have 5 internet connections (two dedicated links with different ISPs and 3 shared links with one ISP) , I need to configure the 5 untrust zones for internet and one for trust how i can configure the VR and how i can i use PBF per group of users. and create a backup link in case the first internet link goes down.
PA currently doesnt support ECMP according to:
which gives that if you wish to use all your 5 internet connections at once I would suggest you to use a router in front of your PA to do the routing and from that router use a single linknet which you then route the /24 or whatever you have assigned towards the PA unit.
This way the PA unit wont have to care about which connection was/is being used - for redundancy you can setup aggregated interfaces.
The result would be:
1) Internet (5 x connections)
2) Router (BGP preferly, but static would work aswell towards your ISPs)
Your router would have a routing table similar to (regarding PA):
x.x.x.x/24 next 10.0.0.1
while your PA device would have:
0.0.0.0/0 next 10.0.0.6
Edit: Ahem *coughs*, highest usuable ip in the range 10.0.0.0/29 is 10.0.0.6 and not 10.0.0.7 which is the broadcast but I think you already got the point 😃
Many Thanks brother Mikand for your reply.
my concern we have 5 connections in these connections we have 2 dedicated internet links with 25m and we need to configure the 5 untrust zones and use PBF to add rules like IT group will forward to dedicated link number 1 which has 25mb and configure another rule for IT group to use dedicated link No. 2 in case first one goes down. and another AD groups we will decide to which link they can leave using PBF.
LAN ------------ PA -----------------untrust-1
for this scenario we supose to use 6 interfaces one as trust (LAN) and 5 untrust (Internet zones).
for this scenario could you please inform me what is the best practice?
