Kimsufi 2G and failover IP (technical question)

nikc

I'm wondering if someone can help me / advise if something is possible.

I have a UK Kimsufi 2G that I bought to use as a OpenVPN-AS (mainly VPN, but also some other stuff) so I can get a UK IP. Sadly I didn't check properly and found out its in France, so I purchased a UK failover IP ....

What I am trying to figure out is can I force all of my outbound traffic (or even just the VPN traffic) to appear as though it's coming from the UK failover IP or should i just give up ?

Cheers

Just switch the main IP to the UK IP address.

Apparently not possible the OVH guys are telling me ...

@nikc Why not? You just order a failover IP and select UK, you should then be able to map and assign that to your dedicated server.

Right? I'm sure I've done this before with UK IPs..

nikc

Yeh done that, followed the instruction to setup the failover as eth0:0 (UK IP) but my outbound traffic still comes from the IP assigned to eth0 (FR IP) ....

AsadHaider

@nikc Set it as the main IP for eth0.

What program are you trying to use the UK IP with? Bind it to the UK IP or set that as the outgoing IP.

cosmicgate

Perhaps you did not go to the AS configuration and set the interface as eth0:0 and reboot?

This works just fine, I've tried it before too.

Flipping the IP works fine or ?

MartinD

Yes, just assign it to eth0 and drop the other IP completely and it'll work.

Keep the same GW etc etc ? literally just swap it over so the old IP is ?

Wintereise

Yes, @nikc.

The IPs may be from different subnets, but your GW still stays three.octents.of-main.ip.254.

nikc

Didn't work changing the IP ... it's just fell off the net and I had to rebuild :(

Why don't you just connect over IPv6 when experimenting with changing IPv4 addresses.

Wintereise

^ That too.

You can use the 2nd IP address for OpenVPN traffic by setting it in the /etc/openvpn server conf file:

local {ip_address_to_use}

And also set it for the iptables nat rule:

iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -j SNAT --to {ip_address_to_use}
