Having more than 1 external IP is causing issues with a website?

[R.O.S.S.I]

Hi all, at my place of work we have 3 external IP addresses which we use for various public facing pages such as webmail, remote access etc.

We have been trying to log into a website for a while with a certain company and have been having no joy and they say it is due to us having more than one external IP and it not being static.

Does anyone know any way around this? Or what I can do to remedy it?

You may need to configure things so that only one of your IPs is used for outgoing traffic.

I have something similar with my dual wan at home. If they dont have a browser ''keep me logged in'' checkbox i suggest you create a firewall rule to route outgoing traffic to that site/ip down a certain line/wan, unsure what you using to bind your connections...im using pfsense.

Your system might also have a ''sticky connections'' option which will keep the same traffic down the same line essentially keeping you logged in.

Yeh I was thinking is there a way to route all the traffic through one IP but I wasn't sure if that was possible. Do either of you know how to achieve this on a Draytek 2820?

Are all three IPs on the same connection or are you using WAN 1 / WAN 2 on the Vigor?

We're using WAN2 which is for our fibre connection. All the external IPs are on this.

On a 2830 you do the following:

WAN
Internet Access
Details Page
WAN IP Alias
Join NAT IP Pool (just leave one IP ticked).

I thought it could possibly be something to do with this, i've removed all but one of the IP's from the NAT IP pool and will see we get on!
