Your dept., you're adept. From: Andrew Kopp [mailto:[email protected]] Sent: 14 April 2020 14:31 To: [email protected] Subject: Re: Multiple WAN Network Interface
This is a problem at the networking level, any OS will have the same issue. You will have a return routing problem regarding default gateway on the server - unless you are going todo some creative NATing with automatic return route scripting (which is not very good tbh many many painful issues with such an approach) The example below assumes that your default gateway on the server is WAN1 - When client A uses WAN1 URL, the server will return data via default gateway on WAN1. No problem. - When client B uses WAN2 URL, the server will see the initial connection request but any response wil still be sent back via default gateway on WAN1. This will break your connection and eat up bandwidth on WAN1 that you did not originally intend. This issue stems from the simplicity of TCP/IP and the OSI model separating each layer. The application layers have very little control over networking and do not control routes, where as the networking layers have no idea what you are trying to accomplish on an application layer. NATing was born out of the need to be able to control the network on a session level. If you have such an environment you should consider WAN bonding from solution providers such as Mushroom Networks or Peplink (no affiliation - just experienced with both products) If you cannot do this, you are better off running multiple dedicated instances of Guacamole for each connection. You might be able to accomplish this using docker on the same host, but I am not familiar enough with the docker network stack. If you really want to go with the NATing solution, you will need multiple Apache proxy listeners/ports - one for each connection. You will then need to separate each interface traffic via reverse NAT rules and port forwarding. Even when this is perfectly configured, an outage on one of the connections will put you back to the drawing board tearing your hair out reconfiguring the stack. Your time is probably worth a lot more than a bonding solution.

WAN 1 \ WAN 2 --- Guacamole Server - LAN WAN 3 / Suppose each WAN link have 10Gb bandwidth, Then I get different URL for different department users: Account: https://WAN01.example.com:8443/guacamole/ Sales: https://WAN02.example.com:8443/guacamole/ IT: https://WAN03.exmaple.com:8443:guacamole/ In theory , I have 30Gb WAN bandwidth? In case one of WAN Link is dead, I just update the DNS records to redirect the traffic. Any comments?
