Hi. Need help for 3 Wan Setup…



  • Hi. Currently we are using Pfsense(1.2.3)with 2 wan and 1 lan for our 29 workstation without any major problem. Its working nice. Now we are planing to attach another wan.

    But problem is there are no place to put our Third ISP DNS. I know we can use Public DNS such as OpenDns Or Google or other Public dns. BUt In my experience and also i read that ISP DNS works much better than Public DNS. SO please tell me what and how i can solve this. It will be great Help.

    I will wait for kind Help. Thank you…



  • hi. Again. Please I need Kind help. I know how to setup dual wan with two wan. And currently i am using multi wan setup for my Cybercafe. My confusion is where should i put Third Dns and what would be the third Static route.

    Because Currently I am Using two DNS server from my first Two ISp DNS. And also Static Route from my first two ISp Dns. And Monitor Ip is my Two Modem Getaway. ANd its working flawlessly. Loadblance  and Failover.

    PLease help me to clear about this. so that i can use its maximum performance. I am waiting for kind help. Thank you Very much. God Bless all.



  • Third ISP DNS

    Use the fit123 package or manual edit config.xml

    AFAIK most ISP dns are also public so do a google search for an ISP dns in your area.



  • Thank you Very very much for your kind help. Yes as you said i will follow your advice. and then how i get performance i will update it here. Actually I do depend a lot on pfsense. Currently we are using 30 pf-sense box in 30 different Cybercafe. Only One cyber cafe we are using multi wan setup.

    And tell you the truth it's awesome. I have never seen something like that. I have Pfsense Book also. And now i am thinking I may go for Commercial Support also form Pfsense Team in Future. Thank you And God Bless all the member of Pfsense Team For Such a Product Bring for us.



  • Thank you Very very Much Mr. Perry. It's work. and working flawlessly. I did follow your advice and i got 3rd and 4th DNS option.. Last night i did. And its working very High way. Thank you very much again.

    Sir I have few question for you. It would be great if you have time to answer. Those answer will increase my knowledge about Pfsense.

    1)About the DNS. Under DHCP Server Option. I always see a two Field for Dns. Those field make any difference for performance? Because there i don't put any DNS.I hope you will clear little bit about these two field for me.Thank you.

    2)About Rules. I have created rules on lan like this. My first Rule is wan3, then wan2 then wan1. then loadblance. These are my only 4 rules at this moment. Is this right combination? Thank you.

    I will wait for the answer. Take care and God Bless Sir.



  • 1)Nope, just leave them blank

    2)Sounds like you only will be using wan3 with that setup. From page 145-157 in the book you should get the needed info on using policy routing with load balacing pools or failover pools.



  • Thank you Mr. Perry once again for your kind respond. about My Rules actually I did mistake when i have written this line " My first Rule is wan3, then wan2 then wan1. then loadblance."

    It should be like this.My first Rule is wan1, then wan2 then wan3. then loadblance. These are my rules.

    MR. Perry I think My multi wan is working correctly. Because i am getting very very awesome performance. But I am Sure it could be more better and better if i get suggestion from you.

    For your Information. I am putting my all the picture of my setup. Please check this kindly and if you see any thing wrong let me know. So that i can correct it.

    I will wait for your answer sir. God Bless

  • You could disable the first 3 rules and only active them when you need to access there modem.
    Before the loadbalancing rule create a rule with destination port 443 using a Wan2FailsToWan3 failover pool.
    IMO the monitor ip should be an IP outside your ISP network like opendns or google.



  • Hello. Mr. Perry. Thank you once again for your kind respond. OK as you said tonight i will follow your advice.
    But tell you honestly when ever i try to put DNS(My ISP DNS) Ip As a monitor ip. I saw its Delay time much more than Default Getaway(Modem) Ip. Thats why I select Modem Getway ip as a monitor ip.

    But i will try to check this as you said. Thank you very much. God bless
