Dear Friends

I have setup a 1km wireless link with the help of RB433AH having 23dBi Grid antenna as client and RB433AH having 12dBi Omni antenna. everything working fine i can ping and test bandwidth it is perfectly fine and getting 8Mbps speed on average.

But the problem is this that i have assign a real IP to one of my device. I can ping my Gateway but unable to ping the device assign IP address. can someone help me in this regards.

Are you talking about the Mikrotik router itself?

Check the broadcast address in your IP -> address settings and make sure it is set accordingly...

communicaters · Thu Jun 09, 2011 9:06 am

Dear friend

every thing is set accordingly because it is assigned by the ISP and there is no doubt about it because I am pinging the Gateway as well.

Do you have a default route set? 0.0.0.0/0 to x.x.x.x

Do you have NAT anywhere in the system? Have you enabled masquerade? Need a lot more info to answer that question.

communicaters · Thu Jun 09, 2011 5:58 pm

Dear Friends,

Yes I have set the routing table as well but can not resolve my issue.

I only configure my router's Wireless, Bridge and LAN interface IP nothing else has been set.

but still unable to get connected. I even can not ping my remote AP's LAN IP as well.

You missed the part where it says "need a lot more info to answer your question". Just saying "nuh uh" doesn't get anyone anywhere.

Put yourself into everyone else's shoes. You can't figure out what is going on and you have access to the system - how is anyone else supposed to figure it out for you when they can't even look at the devices in question? If you want help other than wild guesses, post some details.

Start with the output of "/ip address print detail", "/ip route print detail", "/interface print", "/ip firewall export", and an accurate network diagram.

C'mon fewi, sometimes guessing is fun

Diagram is simple One is Bridge and second is Station
Bridge is installed at ISP and Station is in my site

Please advice me what to do that i can access the Internet

From my office I can access all the device which are installed in the ISP and can see in my neighbour.

Remove the 10 dot addresses, they are unnecessary. You don't have a point to point routed link, you're bridging. Assign the public IPs directly to the bridge1 interfaces. Then try again.

What IP address on the public IP network is the default gateway for clients?

Dear fewi,

What IP address on the public IP network is the default gateway for clients?

I can not get what you want to say can you write code for this how i can assign the Public IPs directely to the bridge1 interface.

I have these 3 Live IP's xx.xxx.140.138,xx.xxx.140.139,xx.xxx.140.140 and the Gate way is xx.xxx.140.129

Please tell me clearly what to do

Thanks

do not know if this is what you need, this is a tutorial I made for my classmates, I did it with a program called Wink, I hope you serve is the only thing that is in Spanish.

I have also one of how to do nat, if you served the last I can go the other.
Greetings from Nicaragua.

fewi · Sat Jun 11, 2011 1:37 am

I don't see what those 3 public IPs you're talking about now have to do with the configuration snippets you posted. Hopefully someone else can help you. I'm confused.

communicaters · Sat Jun 11, 2011 10:36 am

Dear Friends,

Please tell me the code to establish a Bridge connection. One on ISP site and one on client site.

ISP assign me the 3 Live IP address

I have these 3 Live IP's xx.xxx.140.138,xx.xxx.140.139,xx.xxx.140.140 and the Gate way is xx.xxx.140.129

Please help me
