MikroTik

Hello Guys,
its been a while since i was here.
i have just completed an upgrade to one of my oldest networks
i have installed a CCR1009 as router and and 2 CRS as switches among an array of mikrotik ptp radios etc.

the problems i have.
network:
3WAN: 2 adsl (1 static public IP one dynamic) + 1 sat ( 2 public ips allocated).
I manage the domain and have mapped the IP address to various subdomains for mailservers etc.
Lan: Hotspot manager for users login/ some offices have routers to isolate their traffic e.g. finance, management etc

1. Public IPs: I would like to port the mail server to be used online |( out of the office)
Q. I have tried port forwarding etc but it works for like 2-3 days and then dies ( no access to the port locally and online) what is wrong?

2. the 3 wans are on PCC with the lan on a hotspot manager ( use it for user login and bandwidth management)
Q. I would like to map the mailserver in the lan to resolve the public IP of the server in the LAN. I.e. 197.x.x.x. should resolve to 10.x.x.x while in the LAN. but works as normal while outside the lan where 197.x.x.x is portforwarded from the server 10.x.x.x. Tried a few scenarios like static dns in the dns setting but it does not resolve in the Lan any ideas?

3. Link optimisation.
i have 2x2MB on adsl <3mb on satellite.
how can utilise all these link capacities. with the network setup you have heard mentioned. Bonding, loadbalanceing what is the way out?

will try and draw the network and post as well. I would like some questions so i can get down to specifics if possible.

the plus side is that the CCR and CRS ( as switches) + some RB260GS have helped improve the network through put tremendously with previous network lags being a thing of the past and troughput to the inhouse NAS improving as the backbone is on gigabit ethernet.

Due to the latency differences I would setup load balancing on the two adsl. I would then forward the mail server through the Sat connection as mail services not heavily affected by the latency. Your users will this way have access to their mail from outside and will have a good browsing experience.

hi,after lots of fighting and scripting managed to LB all three links,
However I am inclined to try the solution from dgnevans.
This setup is for a country with extremely unreliable internet i.e. downtime in the days/month rather than hours.
Would it be possible to have the satelitte as the connection of last resort if the 2 adsl connections go down?
And would the portforwarding through satelite work in that scenario as well?

just a thought as all the PCC Portforwarding solutiosn are quite the script to do.

suggestions would be of great help.

I have a similar setup that I use. I have configured connection sharing amongst all my connections. I just disable the satellite connection when terrestrial is working normally. Should terrestrial go down I manually enable satellite and disable the Terrestrial. This could be done automatically using scripts but prefer to control it manually. I always have Mail server going through most stable connection. In our case the satellite connection. This ensure mail always flows.
