HI All,

Hi!

It is possible to setup multiple Network WAN interface on Fedora Linux box, so 
it can increase the total WAN bandwidth and HA?

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.

Furthermore I have not yet understood how you want to set that up? And why?



If you want to do HA, why not









HA with haproxy and keepalived is easy, via DNS a nightmare.

Uh. No. Don't do that. DNS has an up to 24h "lag" since Windows tends to cache IPs and you do not want to teach your users to flush that. :) You can do a link aggregation group to pseudo-"bundle" bandwith...but discussing that is not for this list. WAN 1-3 -> haproxy -> department-specific guacamole servers with load balkancing groups and seperate DBs (if needed) -> as many guacd-instances as you like/need for balancing. You can "filter" the target guacamole by url: example.com/accounting goes to guacamole 1, /sales to 2 and so forth... You set up the ha-proxy with a keepalived and example.com will be a floating IP shared between the proxies. Not quite sure what the goal of your setup is..:) Separation by bandwidth is hard to do w/o network equipment, separation by url easy.
