Region : Argentina

Model : TL-ER6120

Hardware Version : V1

Firmware Version :

ISP :

I have a TL-ER6020 firewall product that I have setup with an IPSec VPN
between 2 sites. Site A <-> Site B

Site A : TL-ER6020 (192.168.0.0/24) with static route to 10.224.14.0/24 via
192.168.10.1 gateway address via WAN1 (hopefully through VPN on that
interface).

Site B : Cyberoam CR35wi (192.168.10.0/24) with working static route to WAN1
interface (192.168.51.1).

My aim is to get traffic from Site A through the VPN via static route to
Site B which will forward through WAN1 interface to network 10.224.14.0/24.
The static route for Site B is working for it's local subnet at present.

10.224.14.18 (destination address) -> Site A (192.168.0.1) -> (static route) -> VPN (WAN1) -> Site B (192.168.10.1) -> WAN1 (192.168.51.0) -> 10.224.14.0/24

Can traffic be routed through the VPN via static route or is there another
way to do it? Or is it not possible with the TL-ER6020?

1. You need to provide a better diagram than that.

2. It looks like you have the destination network address on both LAN sides of both routers. If that's the case, routing will never happen.

Image attached I hope this makes it clearer.

I believe I understand what you are attempting. Correct me if I am wrong;
1. you have multiple networks attached to Router B?
2. Router B - cyberoam CR35wi (192.168.10.0/24) & (10.224.14.0/24) ?
3. you have one network attached to Router A that needs to connect to all networks on Router B?
4. Router A - TL-ER6020 (192.168.0.0/24)?

IPSec does not work by routing tables.
IPSec encapsulates/encrypts one network's packets (Intranet) for destination over unsecure networks (Internet) to another network (Intranet) then unencapsulates/decrypts packets. Then any internal static routes are used to route packets for different attached networks.

A rule for each network's packets is needed.

On Router A:
You would have to create a second tunnel IPSec Policy with the source network (Router A - TL-ER6020) 192.168.0.0/24 to destination network (Router B - cyberoam CR35wi) 10.224.14.0/24.

On Router B:
You would have to create a second tunnel IPSec Policy with the source network (Router B - cyberoam CR35wi) 10.224.14.0/24 to destination network (Router A - TL-ER6020) 192.168.0.0/24.

Here is a more detailed map of the topology.





I am hoping to create a static route from 192.168.0.0 to direct traffic to the CR35wi (192.168.10.0/24) and it will in turn use its static route to forward to the destination at 10.224.14.0/24.

The diagram is missing some components;

Does, Router A (192.168.0.0/24) connect to Router B (192.168.10.0/24) via WAN 1 using IPSEC/VPN ?
Does, Router C (192.168.51/0) connect to Router B (192.168.10.0/24) via WAN 2 using IPSEC/VPN?
How do Router C (192.168.51/0) connect to Router D (10.224.14.0/24) ? IPSEC/VPN/LAN?

Send me a private message with details.

Does, Router C (192.168.51/0) connect to Router B (192.168.10.0/24) via WAN 2 using IPSEC/VPN? WAN2 (no VPN, private wide area network)
How do Router C (192.168.51/0) connect to Router D (10.224.14.0/24) ? IPSEC/VPN/LAN? Private LAN

This might be clearer -

Did you create the two IPSec Policies mentioned above?
