How to setup a redundant ip connection?
Hello,
I have 2 ip's from 2 providers and I wanna get a redundant connection if the main provider will fall.
The second (backup) connection, ip2, is from one provider who support only pppoe login, so I've installed the 'rp-pppoe' yum package and I successfully connect to the network.
Now I have em1, which is the main connection, and the ip1 is set in Home > Server Config > Basic WHM Setup.
And em2, which is the backup connection.
How can I manage or where can I specify the backup connection ip2 in WHM?
Thanks,
Adrian

I don't believe this is possible if I'm understanding correctly you want to specify the IP address the backup connection comes from on your server? 0 -
Yes, I wanna add a second connection from another ISP in case the main ISP will be down. How can I manage this situations? :) 0 -
It's the 3'rd time when my ISP was down for ~3-4 hours and I need a backup internet connection in case this situation will be back. Please don't tell me that the internet connection can't be backed up and ISP is a single point of failure :) I think having a redundant internet connection is some basic principle on how a datacenter works :) 0 -
This is a discussion you need to have with your datacenter, it's not something we can help you with. 0 -
They give me 2 ip's from 2 different providers :) What can they do more than that ? :) And how other cpanel hosting providers manage those situations ? 0 -
The IP's need to be routed at the Datacenter properly, this isn't something that cPanel can manage. 0 -
ok, thanks ... is somewhere any guide on how to do this? or example? or how others manage this situations? * how to properly setup ip routing on dc for cPanel if the main internet connection ( the ip with the cPanel license ) is down? 0 -
I don't have one as this is something that is dependent on the datacenter/provider. This is something you'd need to contact them for, cPanel has absolutely no control over these items. You can add a new IP address to cPanel but that is dependent on the IP address being routed properly which happens separately. 0 -
In the secure (router) mode, the client-side and server-side VLANs provide the fault-tolerant (redundant) connection paths between the CSM-S and the routers on the client side and the servers on the server side. In a redundant configuration, two CSM-S modules perform active and standby roles. Each CSM-S contains the same IP, virtual server, server pool, and real server information. From the client-side and server-side networks, each CSM-S is configured identically. The network sees the fault-tolerant configuration as a single CSM-S. Configuring fault tolerance requires the following: " https://www.cisco.com/c/dam/en/us/td/i/templates/blank.gif
Two CSM-S modules that are installed in the Catalyst 6500 series chassis. "https://www.cisco.com/c/dam/en/us/td/i/templates/blank.gif
Identically configured CSM-S modules. One CSM-S is configured as the active; the other is configured as the standby. "https://www.cisco.com/c/dam/en/us/td/i/templates/blank.gif
Each CSM-S modules connected to the same client-side and server-side VLANs. "https://www.cisco.com/c/dam/en/us/td/i/templates/blank.gif
Communication between the CSM-S modules provided by a shared private VLAN. "https://www.cisco.com/c/dam/en/us/td/i/templates/blank.gif

Connection redundancy by configuring a link that has a 1-GB per-second capacity. Enable the calendar in the switch Cisco IOS software so that the CSM-S state change gets stamped with the correct time. The following command enables the calendar: Cat6k-2# configure terminal Cat6k-2(config)# clock timezone WORD offset from UTC Cat6k-2(config)# clock calendar-valid Check this0
