VPN Site to site IPSEC
-
Hello, I want to make a IPSEC connection site-to-site between 4 sites with IPSEC, and I want the 4 sites to see each other.
At the moment, the site to site tunnel with the server and the other sites works correctly, but the B, C and D sites can not be seen between them.My question is, on the server side, should I add 3 VPN servers?
or do it in phase 2?
Or create 1 alone and configure it in some predefined way?And on the client side, how do I see / configure the other sites?
All have a range:
10.1.0.0/16 - HEADER A - Server
10.2.0.0/16 - HEADQUARTERS B
10.3.0.0/16 - HEADQUARTERS C
10.4.0.0/16 - HEADING D -
Wouldn't you create IPsec tunnels on all the routers going to all the other routers then run FFR to look after the routing ?
-
Because the routing table has no effect on IPsec so FRR won't do you any good there.
You want to do it in your Phase 2s.
If a network should be reachable from a site, there should be a Phase 2 for it.
For instance, For the tunnels from A to B:
On A:
Local Network: 10.1.0.0/16, Remote Network: 10.2.0.0/16
Local Network: 10.3.0.0/16, Remote Network: 10.2.0.0/16
Local Network: 10.4.0.0/16, Remote Network: 10.2.0.0/16On B:
Local Network: 10.2.0.0/16, Remote Network: 10.1.0.0/16
Local Network: 10.2.0.0/16, Remote Network: 10.3.0.0/16
Local Network: 10.2.0.0/16, Remote Network: 10.4.0.0/16Etc.

and if I only have an ipsec connection between headquarters A and D
but in the headquarters D I want to see the headquarters B
all other venues are configured and seen with WIMAX
how do I pass the routing table?attached network image

and if I only have an ipsec connection between headquarters A and D
but in the headquarters D I want to see the headquarters B
all other venues are configured and seen with WIMAX
how do I pass the routing table?You put the local and remote networks on that tunnel.
On the tunnel between A and D you would make a P2 for D to B.

I do not understand you
 -
If you are going to refer to sites as A, B, C, and D it would be helpful to have that information on your diagram.

hello, I modified the scheme
I have added the HEADQUARTERS E
This is really my topography
I currently have a vpn Ipsec between the HEADQUARTERS A and E
all other HEADQUARTERS , except E, are communicated by WIMAX
I want to pass the routing table to E headquarters, from the others HEADQUARTERS so I can see them all
 -
So you already have a Phase 2 entry on the VPN for this:
10.1.0.0/16 <-> 10.5.0.0/16
Make 3 more:
10.2.0.0/16 <-> 10.5.0.0/16
10.3.0.0/16 <-> 10.5.0.0/16
10.4.0.0/16 <-> 10.5.0.0/16Obviously with the reciprocal entries at Site E.
Add routes to sites B, C, and D those sites for 10.5.0.0/16 with a gateway of whatever they talk to at site A.
Make sure all necessary firewall rules pass the desired traffic.
-
and how do I do this without leaving the connection by wimax with the others HEADQUARTERS ?
-
What?
-
if I configure this in VPN tunnel,in both extremes
10.1.0.0/16 <-> 10.5.0.0/16
Make 3 more:
10.2.0.0/16 <-> 10.5.0.0/16
10.3.0.0/16 <-> 10.5.0.0/16
10.4.0.0/16 <-> 10.5.0.0/16I lose communication by wimax between headquarters
A-D
A-B
A-C
….....I do not know if I explain
-
No you don't.
10.2.0.0/16 <-> 10.5.0.0/16 is not the same thing as 10.2.0.0/16 <-> 10.1.0.0/16
