Re: Really strange problem with Hairpin NAT

Thanks for spending time on my issue and thanks for asking the right question :D Off course I was to blame. I had by error activated a chain=srcnat action=masquerade rule at the very bottom of my NAT rules. It was part of some experiments i did a long time ago. I had simply forgotten all about it an...

Really strange problem with Hairpin NAT

I've configured hairpin NAT in order to access my SSH server running on an internal LAN server. On my SSH server I've set up some ip blocking rules to safeguard against brute force attacks. I thought I had it all configured correctly until one day I noticed that I could no longer connect to my SSH s...

Re: Advanced Home Setup - DMZ + DUAL WAN

That's a good tip. Begin with the most restrictive rules and then add ways around it when you need it. I'll make that my basic rule from now on.

Re: Advanced Home Setup - DMZ + DUAL WAN

Yup. Below all my other forward rules I added a foward connections with State = new and at the bottom of the chain I did as you suggested a catch all "drop forward". And It worked. Everything works as expected. Thanx.

Re: Advanced Home Setup - DMZ + DUAL WAN

Ooops! You're absolutely right. But i think i have to combine it with a couple of rules to forward "new" connections from my LAN or else i would loose internet connectivity wouldn't i?

Re: Advanced Home Setup - DMZ + DUAL WAN

Well it sure did fix my problem. But as a complete newbie I'm constantly concerned about creating gaping holes in my firewall. So looking at my configuration as a whole do you think it's ok? I'm planning to harden it by adressing port scans issues and trojans.

Re: Advanced Home Setup - DMZ + DUAL WAN

You we're spot on. I think i just misunderstood what you meant by routing to 192.168.1.1 but it came to my mind that all these marks is just something that happens inside the router and not elsewhere. So of course the packages was lost on their way back from my host...well at least i think so. This ...

Re: Advanced Home Setup - DMZ + DUAL WAN

Ok. Maybe i'm just a bit impatient. Sorry for that :D . What gateway should be defined in the route to 192.168.1.1 ? 1.1.1.189 ? Just tried that but no luck. Please do take your time. I'm in no rush. As I said before - i'm just being impatient and I know it's a bad habbit :wink:

Re: Advanced Home Setup - DMZ + DUAL WAN

Anybody? Maybe just a basic example of how to do the NAT, mangle rules and ip routes for a solution with two WANS, a LAN on one subnet and a DMZ zone on another could do. I'll strip my filter rules and start all over on them if I could just get the simple setup working.

Re: Very new to this.

Port 1 is default on your device. Remember to be patient if your ISP provided you with a static IP. Sometimes it will take up to four hours before your ISP registers the MAC address of your new equipment. Only then your new routers gets it WAN IP. I've also experienced ISP's that expects you to call...

Advanced Home Setup - DMZ + DUAL WAN

Consider the following network diagram My LAN.jpg Everything works just fine... well almost :?. Internet traffic from all my LAN clients, LAN servers and DMZ server goes out via 2.2.2.2 (DKTVWAN) just as expected. From my DMZ I can only open new connections to the internet on port 80 and 443. My LAN...

Re: How do i turn off wireless on RB2011UAS-2HnD-IN

The RB2011UAS-2HnD-IN comes pre-loaded with a configuration in which the Wireless interface is the only interface that has a static IP assigned to it. As far as i remember it is 192.168.88.1 correct? Anyway mine came with 192.168.88.1 assigned to the wireless interface. By disabling the Wireless int...

Re: Mikrotik beginner - couldn't find an existing post

I guess you wan't to make your RB751 act as an Access Point. I'm a newbie to RouterOS to so i'm can't tell you how but i'm sure it can be done. Your keyword should be Access Point when you search.

Re: Connect mikrotik to cablemodem - Router + AP

I too have a cable modem and successfully got online using my cable modem. I'm sure your RB750xxx comes with some sort of default configuration pre-loaded. My RB2011 did and I had to connect my my cable modem to ethernet port 1. The wireless was also enabled by default but was unsecured so I had to ...
