Hi,
I need some help please.
I installed the latest RouterOS 6.32.3, on an old PC (dual core intel E4500, 4GB ram, small ssd drive, 2 ethernet card…)
Today, I am connected to ADSL, using the Box provided by my ADSL provider (my provider is Orange)
This Box does modem, and router. and it is somewhere crappy.
I want to replace it, by using a modem (Netgear DLG 2200 in bridge mode) and this routerOS on my pc + a switch.
Config question :
today, I have this config (temporary config) :
internet ↔ the crappy ADSLmodem ↔ the crappy adsl router ↔ 4 crappy ethernet port ↔ RouterOS on PC ↔ switch 8 ports ↔ some Mac computer.
why ? this modem do not accept bridge mode. so, during my test, I connect the routerOS on an ethernet port…
My crappy adsl router IP is dynamic. no choice, my provider do not give static IP.
then, I use dyndns to make the link between internet (my domain name for example), to my Box.
later, I plan to do (when I will have my modem ) :
internet ↔ netgear ADSLmodem - bridge mode ↔ Wan port of the modem ↔ RouterOS on PC (ethernet card) ↔ switch 8 ports ↔ all Mac computer
question 1 : is it possible = can I connect the OSrouter OS with an ethernet card, on the wan port of the modem ?
question 2 : I plan to add 2x pci wifi card (one 2.4 and one 5ghz).
is there any recommandation for any brand or model ?
question 3 : how can I manage the dynamic ip in routerOS ?
nat parameter question :
note : I use only Webfig to do any parameter !
today, routerOS is connected to the adsl router, by ethernet port.
I have no rules on the adsl box : just a static ip given to routerOS computer.
RouterOS forward internet to the switch, which forward it to the Mac computer. this is working.
for that, I set the router os in bridge mode (menu quick set)
ether2 card is connected to the Box (on adsl router, ethernet port)
ether1 card is connected to the switch using ethernet port (switch is connected to the mac computer)
I defined a bridge parameter (menu bridge), to do bride from ether 2, to ether1
I defined 2 port (may be it was automatic) in the menu bridge / port
now, I need to set some NAT port forwarding.
I own a domain name (let say : www.hello.fr), which should be redirected to internal ip : 192.168.1.38
I tried to define a nat, in menu : ip / firewall / Nat :
the parameter are =
chain : dstnat
Dst. address : 90.15.124.87 = current ip of the adsl box at this moment.
protocol : tcp
Dst. port : 80
Action : dst-nat
to addresses : 192.168.1.38
to ports : 80
during my test, my domain name www.hello.fr was redirected to 90.15.124.87
this does not work at all 
(
question :
how could I define properly my NAT for this case ?
thanks you if anyone could help me.
Best regard
Olivier
