ANSWERED How do I set my VPN to bypass VPN when sending mail

Recommended Posts

ok, using Ubuntu 14.04, Thunderbird, VPN through Network manager. Unable to connect to my outgoing mail server.

smtp.secureserver.net / 68.178.213.37 port 465 SSL/TLS . I am unable to connect to it while on VPN (Blocked I assume), turn off VPN and I have no problem. This also seems to be the only port they offer.

Is there a way to add to the settings that anything going to this address to bypass VPN via the iptables and if so how. Tried a few settings and still doesnt work. Or do I need to add a additional Netcard?

First of all, I'd file a complaint with whoever you're with - why would any service block a customer's IP on an authenticated mailserver? Makes little sense to me.

 

Anyway, if you do want to bypass the VPN for this IP, you need to set a route for it. Routes are not handled by iptables.

In NetworkManager, edit your VPN connection. In the IPv4 tab, you will find a "Routes" section.

Add a route for:

Address 68.178.213.37

Netmask 255.255.255.255

Gateway X.X.X.X

 

Replace X.X.X.X with your home router's local address (192.168.0.1, for example)

 

You only need to touch iptables if you're already using it to block non-VPN traffic.

In that case, create a rule that allows outgoing traffic to 68.178.213.37 on your ethernet or wifi interface.

I would file a complaint, But my smtp server is GoDaddy and that would be like pulling teeth. I would prefer not to use them but for reasons I have to because of my email settings and certain things I need to do. So someone at one time (one we need to thank with a hammer or such) used the VPN server to flood out spam mail and got the server banned creating my problem.

 

Before trying what you said I switch to a US server in PA, my god I could of walked the 2400 miles faster than sending a file. But at least the smtp worked. So that leaves it with the IP being blocked on the 1st server for sure. I then tried your settings as you mentioned and almost nothing worked, web pages died, even doing a netstat -r was dead slow at displaying. Here are some of the settings before and after (each labelled below)... The `p3plibsmtp02-v0` is the smtp server. Well after this I changed to another server in CA, `Chort` with out adding the routing and low and behold the smtp worked.

 

By the way, I'm using Charter with 60mbps download speed, so finding a good VPN server is a trick to get close to what is acceptable for speeds.

I wrote a script to do this for multiple websites for use with Network Manager's dispatcher service. See https://www.mankier.com/8/NetworkManager

 

#!/bin/bash
URL_LIST=("smtp.secureserver.net" "anothersite.com" "space-delimited.net")
GATEWAY="192.168.0.1"
 
IP_LIST=()
 
for url in $URL_LIST
  do
    ip=`dig +short $url`
    IP_LIST+=("$ip")
  done
  
for ips in $IP_LIST
  do
    ips=(`echo $ips | tr " " "\n"`)
    for ip in $ips
      do
        ip route add $ip via $gateway
      done
  done

Add in the URLs you need, save it as root in /etc/NetworkManager/dispatcher.d as whatever you want to call it and it will run after connecting to a network.

So how can I make press switches behave like toggle ones ?

 

e.g Landing gear has also a toggle functionality Key binding but not EAC for example. Is there any way to create one for EAC etc ?
