I see two possible scenarios for dealing with the two devices:
Scenario 1
Code: Select all
+------------------+ PPPoe Public IP address +------------+
| |---------------------------------| ADSL modem |
LAN 192.168.10.1/24 | | +------------+
-----------------------| RBD52G-5HacD2HnD |
| | 192.168.88.2 192.168.88.1 +------------------+ Public IP address
| |--------------------------------| RBSXTR&R11e-LTE6 |---------------
+------------------+ +------------------+
Scenario 2
Code: Select all
192.168.10.1/24 +------------------+ PPPoe Public IP address +------------+
+-----------------| RBD52G-5HacD2HnD |---------------------------------| ADSL modem |
LAN | +------------------+ +------------+
-----+
| 192.168.10.3/24 +------------------+ Public IP address
+-----------------| RBSXTR&R11e-LTE6 |--------------------
+------------------+
In the RBD52G-5HacD2HnD I have openvpn configured which authenticates against a radius server. If I choose scenario #2, I could have the RBSXTR&R11e-LTE6 to also start openvpn on a different address pool. Having two openvpn on two different IP addresses would increase reliability a lot.
At this point, I would like to use PCC to load balance the two lines. In https://wiki.mikrotik.com/wiki/Manual:PCC I see that it handles a case that is similar to scenario #1, it has two statically conifgured interfaces while in my case one of the two is a dynamic one. I would like to know if there is a way achieve something similar in scenario #2.
In my head, the steps will be:
- configure mangle to start gathering the connections in two groups
- connections in group #1 would be natted as now over the ADSL line
- connections in group #2 would would receive a ICMP Redirect, to use RBSXTR&R11e-LTE6 as gateway
Therefore, my questions are:
- do you think scenario #2 could work?
- do you know any reference document page explaining how to do this?
- how can I configure RBD52G-5HacD2HnD so that the connections in group #2 receive the ICMP redirect?
- in case scenario #2 is not doable, do you know a way for the RBD52G-5HacD2HnD to use the public IP address negotiated by the RBSXTR&R11e-LTE6?
