Vigor V3300 - Firmware Version is 2.6.0.0 (EN)

Hi,

We've got 2 BT DSL lines, 2 Static IPs. I want to route all our out going emails from our Exchange server out through 1 of the BT lines (WAN2).

Here's what we have set.
Network - WAN
Load Balance Enabled (Auto Weight Enabled)
WAN1 & WAN2 ticked in Load Balance Column.

Network - Load Balance Policy
Protocol SMTP
Souce IP - 10.1.1.3
Subnet Mask - 255.255.255.0
Dest IP - Blank
Subnet Mask - Black
Dest Port Start - 25
Dest Port End - 25
Network Interface - WAN2
Strict Bind - Yes

When sending out an email from a workstation or OWA they are still going out through WAN1 (checking this using the email message internet headers - this shows the static IP for WAN1)

Emails from the Exchange Server are going out via a connector to a specific SMTP server on the internet (our domain host) & not routed via DNS, I have check the settings for this and it's on the default port of 25. I have tried setting the IP in the Dest IP field, but that made no differance.

I am missing something from the policy ?

Thanks in advance

Hi,

We have a very similar setup and similar experiences to you. It appears that 'Strict Bind' is not very strict at all.

I have had better results by setting up the same as you but in the Load balance column, untick WAN2 and set WAN1 as 100%. This should put everything through WAN1 unless you tell it specifically to go through WAN2, eg your SMTP traffic.

Thanks for the response.

This will I guess obvioulsy turn off any load balancing to WAN2 apart from the SMTP traffic?

Trouble is each of the lines only provides a 2Mb connection so we really need to load balance.

Reason for having SMTP on WAN2 is that we have a lot of remote users on WAN1 and we added the 2nd line to help coupe with the traffic from us in the office. I just wanted to make sure that emails went out and in on WAN2 - some of the mails coming in and out can be 10Mb plus ... people never learn.

I guess the other option is to get all the VPNs setup to come in on the WAN2 IP...

yes, it just spilts the traffic rather than balances it.

You would think that in your scenario 'strict bind' should achieve something though - frustrating for you

I would attempt a firmware update, but could do without something else breaking ;)

nevermind, cheers for the responses
