ASA communication form many inside to many outside

moussa.malqui1 — Tue, 12 Mar 2019 08:53:10 GMT

hi all,

how can i make interface vlan2 (GigabitEthernet0/1.1) to communicate with interface tcvpn (GigabitEthernet0/4.1) and interface vlan3 (GigabitEthernet0/1.2) to communicate with interface cacvpn (GigabitEthernet0/4.2)? when i put "route tcvpn 10.240.20.0 255.255.255.0 10.30.60.1" or "route cacvpn 10.240.30.0 255.255.255.0 10.30.70.1" i get error this interface is directly connected, but when i put "route tcvpn 0 0 10.240.20.1' i get communication between interface vlan2 (GigabitEthernet0/1.1) and interface tcvpn (GigabitEthernet0/4.1) and when i try to put route cacvpn 0 0 10.240.30.1 to get communication between interface vlan3 (GigabitEthernet0/1.2) and cacvpn (GigabitEthernet0/4.2) i get this route is already exist.

so what is solution to put many "route interface 0 0 adrs_IP" to get communication from many inside interfaces to many outside interfaces or other possibility to solve that

this is my configuration:

Is this a Lab? Why do you

Marius Gunnerud — Fri, 03 Feb 2017 22:18:04 GMT

Is this a Lab? Why do you have dynamic NAT between all your LAN interfaces? The only dynamic NAT you should have is between your LAN interfaces and the outside interface (internet facing interface). No NAT needed between the LAN interfaces.

You do not need routes to route traffic to subnets that are directly connected to the ASA.

Run a packet-tracer to find out what is stopping the packet in the firewall.

this is not LAN interfaces

moussa.malqui1 — Fri, 03 Feb 2017 23:01:55 GMT

this is not LAN interfaces they are vpn link interfaces (tcvpn,cacvpn) to router in my LAN and outside (internet) but whithout deefault route i didn't get access to vpn applications this is my archetcture: i have sub-interfaces for vpn and sub interfaces for LAN (VLAN)

You do not need default

Marius Gunnerud — Sat, 04 Feb 2017 20:32:20 GMT

You do not need default routes out each interface. the reason you don't have reachability is because the ASA does not have routes to the remote destinations pointing out the correct interfaces. So what you need to do is add static routes for all the subnets and point them out the correct interfaces.

So for example for subnets A and B

route INTERFACE1 A.A.A.0 255.255.255.0 <INTERFACE1 next hop IP>

route INTERFACE2 B.B.B.0 255.255.255.0 <INTERFACE2 next hop IP>

thanks Marius , in my architecture i have 2 hops, what routes i should do my architecture as the following

Could you run a packet tracer

Marius Gunnerud — Mon, 06 Feb 2017 20:27:03 GMT

Could you run a packet tracer

packet-tracer input VLAN2 tcp 10.30.60.10 12345 10.240.1.10 80 detail

Also, can you try to ping 10.240.20.1 from a host on VLAN2.

If both of these are successful then your issue is routing.

thanks Marius , what is the routes i should put in my case ?

route tcvpn 10.240.1.0 255.255.255.0 10.240.20.1 .

this route sufficient or i should add the route:

route tcvpn 10.240.145.0 255.255.255.0 10.240.20.1

regards,

route tcvpn 10.240.1.0 255

Marius Gunnerud — Tue, 07 Feb 2017 16:12:21 GMT

route tcvpn 10.240.1.0 255.255.255.0 10.240.20.1

this route is sufficient. the other route is not needed.
