Pfsense didn't send notification emails over openvpn/ipsec

[ggzengel]

I think the pfsense take the wrong source ip (WAN) for sending emails.
Same thing if dns server behind openvpn or ipsec.

What's the best way that pfsense will use source ip of LAN interface?

From this doc:

As of pfSense 2.1, you can change the binding for SNMP, NTP, the DNS Forwarder, and several other services. 

There are no options.

@ggzengel:

There are no options.

Huh? You need to look deeper in the GUI… Like, Services => SNMP => Interface binding; Services => DNS Forwarder => Interfaces or Services => NTP => Interface(s)

[ggzengel]

But bindings didn't say which IP will be used for forwardings and notification didn't have any.

In this doc:

it :doesn't send the response out through a socket bound to the request packet

The most services have config for source (or used) ip.

The use of a "bogus static route" can have side effects in multi wan and load balancing configs.

Until now is there not a user friendly solution?

I just do not think some 2004 quote related to SNMP is relevant to the OP and useful in any way. (On that note, the SNMP implementation is completely different.)

[jimp]

The quote about 2.1 is for the services mentioned and others that have controls.

For services that don't have binding controls, you still need the route, even on 2.1.

For dnsmasq I found this:

You can control how dnsmasq talks to a server: this forces

queries to 10.1.2.3 to be routed via eth1

server=10.1.2.3@eth1

For smtp.inc fsockopen can replaced like in http://stackoverflow.com/questions/4765269/specify-source-ip-using-fsockopen:

$sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_bind($sock, '192.168.1.100');
socket_connect($sock, 'stackoverflow.com', 80);

I'm not a friend to make the config more complex with unnecessary routing.
