You will never get 6Mbps out of this set up on a single downlad. That requires a special bonding set up from your ISP. You should, however, be able to get two separate downloads at 4Mbps and 2Mbps simultaneously and torrents (which are multiple parallel downloads) may get up to 6Mbps.

When using MultiWAN, unless both your WAN's use the same ISP and the same DNS servers, it is highly recommended to switch to using manual public DNS servers such as OpenDNS or GoogleDNS. If you don't you risk getting very poor DNS responses or failure.

How to switch public dns i dont know it can you help me Line 1 - 218.248.255.209 & 218.248.255.139 and line 2 - 192.168.100.115 so how i put public dns like 8.8.8.8 or 8.8.4.4 can work ?

Your NIC drivers are OK.

Have you changed to manual DNS servers?

I'm afraid I have no real life experience of MultiWAN so I can't comment on your configuration.

Yes i have setup manual dns servers which comes with isp
1) 218.248.255.209 & 218.248.255.139
2) 192.168.100.115

This is my dns setup

And you said earlier that i can get speed on two separate downloads at 4Mbps and 2Mbps simultaneously and torrents how can i do that ? right now my speed getting devided and how can i give weight i have 4mbps and 2mbps line

Thanks in advance

The whole point of manual DNS servers is to avoid your ISP's ones. The problem is that ClearOS will normally pick the first DNS server on the list to send the DNS request to. lets say this belongs to ISP1. Many ISP's only allow you to access their DNS servers from their networks. This means in a load balanced MultiWAN environment your request could go to ISP1's DNS server through the interface connected to ISP2. ISP1 will reject this and you'll get a failed lookup. ClearOS will (may - depending on the response from ISP1) then try the second DNS server on your list which may also be to ISP1 - and this could go through either interface and so on. You can end up with really poor DNS lookup times. The way round that is to use Public DNS servers which will work irrespective of the ClearOS interface used. I have suggested OpenDNS or GoogleDNS, but there are quite a few others. Just google "public DNS server".

Some ISP's DNS servers are public. In that case you are OK, but it is not so likely.

I am working from memory not, but on the IP Settings page there should be a check box saying something like "Manual servers" under the DNS Servers box. Check it. You should then be able to edit the DNS servers. If you can't find it, you'll have to wait until I get to my system.

OK, home now. You need to go to Webconfig > Network > Settings > IP Settings > Select your interface > Remove the check box "Automatic DNS Servers" > Update then you should be able to Edit the DNS Servers.

Hello i did as you said

" go to Webconfig > Network > Settings > IP Settings > Select your interface > Remove the check box "Automatic DNS Servers" > Update then you should be able to Edit the DNS Servers."

INow i cant open any other site than google if i open google its opening but if i trying to open youtube.com , facebook.com and any other site it wont load . it's because i set OPEN PUBLIC DNS so now what i do ?

Right now my DNS is
208.67.222.222
208.67.220.220

and i also tried
8.8.4.4
8.8.8.8

That does not make sense unless your ISP's are blocking them (unlikely) so I don't know what is going on. I flip between using OpenDNS on a single WAN and using my own hosted unbound DNS Server and have no issues either way.

Did you uncheck the "Automatic DNS Servers" setting on both WAN's?

What is the contents of /etc/resolv-peerdns.conf and /etc/resolv.conf?

Yes i have unchecked both WAN's Automatic DNS Server and contents of

/etc/resolv.conf
# Please do not edit this file.
# See http://www.clearcenter.com/support/documentation/clearos_guides/dns_and_resolver
domain clearos.com
nameserver 127.0.0.1

/etc/resolv-peerdns.conf
; generated by /usr/sbin/dhclient-script
nameserver 208.67.222.222
nameserver 208.67.220.220

I am completely stumped at the moment as your resolvers are correctly set up. I am not comfortable with your domain name (clearos.com) as this is a valid domain externally. Please can you change it either to a domain name that you own or to an invalid one such as clearos.lan? I don't think it should interfere, but it will send a whole load of invalid DNS requests to the internet.

When you can't reach any site, is that from a LAN PC? If so, what is the output of "ipconfig /all" from a command prompt on the PC?

Ok i did change the domain name clearos.com to clearos.lan and i yes i can't reach any site from LAN pc expect than google my LAN pc has DHCP & here is output of ifconfig in LAN PC

Ah. I assumed you were running Windows on your LAN. What I am after is what your LAN PC sees as its DNS server (perhaps the contents of its /etc/resolv.conf), and what is the LAN IP of ClearOS.

Also what is the contents of /etc/dnsmasq.d/dhcp.conf?

im running LINUX on LAN yes i get it you want to know what DNS is my LAN PC using

My CLEAR OS LAN IP = 192.168.1.1/24

MY LAN CLIENT PC with DHCP config

I don't see anything wrong with your DNS set up and I can't do any testing at work. There are ways of using "nslookup" and "dig" from ClearOS to determine if your DNS lookups are working OK. If they are working then to problem moves on to a routing/multiwan issue. I will get virtually no time tonight so probably cannot have a look until at least tomorrow afternoon.

You could try a "traceroute facebook.com" and see if it resolves correctly and also see what path it chooses and why it fails.

Doesn't your traceroute show a DNS lookup success but a routing failure somewhere after if-ae-5-2.tcore1.SVW-Singapore.as6453.net (180.87.12.53), unless nothing after the core router responds to pings.

Can you try setting a destination port rule for tcp:443 on one of your interfaces and see if you can browse google or facebook?

Hello Sorry for late reply i was busy bit

I setup fresh install now with default dns set 8.8.8.8 & 8.8.4.4 now i can open any site.

Now you said earlier i didnt get total 6mbps as i have 4mbps & 2mbps line but you said i can get individual 4mbps and 2 mbps so how i can do that what weight should i give both line?

how i know my load balancing are working correctly In Multi-Wan both are Online ip and dns are same as previous.
