Internally route devices to WAN
-
Hi folks,
So I'm needed some help, I'm kinda not sure about this, So I have two instances of Haproxy and two Firewalls with two WANs all working fine but I'm wondering if its possible to setup a Route for certain devices to point their host directly to WAN or WAN2 instead of the VIP of the load balancers.
Why?
I have a Mail Server that is only used through Haproxy for 443 for Webmail and ActiveSync however when using mail.fqdn.com it points directly to the VIPs IP so smtp and imap doesn't work internally only if I change the hosts in Windows, MacOS or Linux however I can't do this on iOS or Android devices. smtp and imap Ports 587 and 993 works externally which Points to either WANs.
So i was wondering if I could point mail.fqdn.com to WAN internally for smtp and imap protocols to work for certain devices without changing the devices DNS to external DNS Servers.
Regards

You can point any fqdn to where ever you want to point it.. If your clients are using your internal dns - just create a host override in unbound, to point to whatever IP you want.
-
@johnpoz how can I point my phone to the WAN for mail.domain.com though without pointing everything on the VLANS?
-
@VioletDragon what does your phone use for dns? Out of the box any dhcp client that gets an IP from pfsense would point to pfsense for dns..
So create a host override.. pointing mail.domain.com to whatever you want..
Any device that asks pfsense for dns would get that returned..
if you point your clients to some other internal NS, that is authoritative for your domain.com - then you would need to edit/create the record there.
-
@johnpoz My Phone's using the DNS from pfSense DHCP. However i want to Point mail.fqdn.com to WAN IP for certain devices such as my phone, iPad and Laptop nothing else. Mail Server is hosted internally which is using the same DNS as my Phone.
-
@VioletDragon you can do that with a view.. Where only specific IPs get returned specific answers.. You could create dhcp reservations for these devices. And then create a view so those Ips get whatever IP you want for some fqdn.. ie your wan address vs the local IP..
You can not create views in the gui of unbound - but you can create them in the custom options box.. if you want I can put up an example tmrw, or find the threads where I have done that in the past.
-
@johnpoz Yeah could you let me know how to do that?

@VioletDragon here is a post I did way back in 2017 going over it
https://forum.netgate.com/post/684870
I think I have done a few of them showing examples on how to do a view.. But sure tmrw I could prob setup where normally dns resolves 192.168.9.10 for say my nas, but if you come from a specific IP, set a reservation for my phone to always get same IP.. You would prob need to turn off mac address changing that phones like to do these days.
And then when the phone asks for that fqdn it would get say 1.2.3.4
Be easier if you have a specific vlan for wireless devices like phones and tablets - then you can have anything coming from that IP range get the view IP, and you don't have to setup any reservations..
-
@johnpoz Thanks for the reply so if i'm correct this should be as follows,
server:
access-control-view: 192.168.9.100/32 testview IP of Server
view:
name: "testview" Name of Server
local-zone: "local.lan" static Vlan of Phone
local-data: "test.local.lan. 90 IN A 10.10.10.10" IP of wanAm i correct?
-
No that would have only 9.100 resolving that.. Pretty sure I gave pretty good instructions and examples of it working in that post.
local.lan wouldn't be a vlan, that is the domain..
if a 192.168.9.100 IP did the query it would get back that 10.10.10.10 address
your access control would be the IP range of your devices, say 192.168.9.0/24 now any device coming back 192.168.9.x and asking for test.local.lan would get back 10.10.10.10
You prob want to change local-zone to domain.com
and your local-data would be the IP you want mail.domain.com to resolve to say 1.2.3.4 - whatever you wan IP is you want to send them too. -
@johnpoz so something like this?
server:
access-control-view: 192.168.20.0/24 IP of Laptop
view:
name: "mail" Name of Server
local-zone: "mail.domain.com"
local-data: "mail.domain..com. 90 IN A 10.10.10.10" IP of wan -
@VioletDragon not quite..
the zone is the domain.. domain.com
the local-data is correct if your wan IP was 10.10.10.10
And its not name of server, that is the name of the view your creating..
If your laptop has say IP address 192.168.20.x then it would resolve mail.domain.com to 10.10.10.10
-
@johnpoz So does this look correct? I have taken some info out.
-
@VioletDragon take that 2nd server: out and you have ..com not sure if typo or just taking something out..
And you might want to up the TTL?? Or your going to get a lot of queries - 90 was just something I used in my example.
Oh and this line is wrong
access-control-view: 192.168.9.100/32 testview
In your above where you have IP of laptop, it would be mail which is the name of your view
Here
You forgot the zone type as well, do you look up anything else in domain.com - from external? If so then that would be transparent zone vs static zone, etc. But with a view don't think it matters.. But you have to set the zone type.
Here I moved it to the top of my custom options
Set a different longer ttl and changed it what looks more like a public IP

SG-4860 24.11 | Lab VMs 2.7.2, 24.11 -
@johnpoz I will give this ago and report back to you.
192.168.20.0/24 is the IP Range of the VLAN.
Regards
-
Right so if you want only the laptop to see that view you'd set a single IP there rather than the subnet.
-
@stephenw10 yeah that was my first example with the /32 - but pretty sure he has multiple mobile devices, etc. Vs handing out specific IPs to devices and listing all the ips that you want to use the view, using a cidr is simpler.. Unless of course you have IPs in that range that you don't want to see the view.
-
@stephenw10 I want multiple VLANs to see this, i.e Guest Network, LAN and WIFI network.
Regards
-
@johnpoz Just a quick question, how can you do this for multiple VLANs?
-
@VioletDragon just set the view for whatever source IPs you want be that a /24 or a /20 etc.. you can also create multiple views, etc. if you want some range of IPs to get this result, and some other range of IPs to get a different one, etc.
