Port Forwarding setup frusterations with Dynamic IP (home service) on RB450G
I'm very new to MikroTik gear and having a heck of a time trying to get simple port forwarding working on my RB450G. I'm using this as my home router after getting sick of crappy home level gear failing and crashing on me (linksys, netgear, etc.). I'm upgrading from a Linksys WRT120N where port forwarding was as simple as going in and telling it which IP to forward to.
I've done a fair amount of searching and reading threads here as well as familiarzing myself with the MikroTik interface. Using WinBox, I've got the router up and running, changed the internal IP and DHCP to my prefered address space, setup custom DNS, NTP, and upgraded the system to the latest 5.18 code. As this is residential service, I have a DHCP (dynamic) IP from the Internet Provider.
All of this is working great and I've seen a fair speed increase over the Linksys in Internet and LAN traffic. Plus the thing doesn't feel so hot I could cook eggs either.
I have three systems that I want to forward services to:
- Windows RDP 3389 Internal IP 172.27.27.251
- Linux web server 22, 80, and 443 Internal IP 172.27.27.252
- Synology NAS 1194 and 1723 Internal IP 172.27.27.254
The internal IP of the router is 172.27.27.1
All of the examples that I could find through searching specify a static external IP to setup the port forwarding. In this case, I have a Dynamic IP and that won't work long term.
This is a fresh config on the RB as well, so I don't even see the DST-NAT chain in the Firewall screen under NAT. Trying to set it up asks for an external IP and won't accept an inferface name.
If I try to just setup a new port forward rule, I actually don't see the "to-address" field anywhere, just an "address list" field and not sure what to set for the action pull down.
My next thing will be to just try command line and paste in some modified commands from the Wiki, but I think that I'm just overlooking some obvious config steps.
I'm hoping that some of you most experienced gurus can pity a newb and spell out everything that needs to be done for port forwarding on a Dynamic IP to get this to work from a fresh config.
Thanks
