MultiWan - OPT1 (WAN2) doesn't work [Solved]

Raul Ramos

Hi

I have 2 WAN one pppoe other is a static connection (try DHCP) to a LTE modem. From pFsense Box i can ping and do DNS lookups fine. From clients i can't.

I have installed pFsense 2.3 on a hyper-V Machine like the version 2.2.5, backup and restore from 2.2.5 to 2.3 built on Tue Dec 01 11:48:28 CST 2015.

Try to add a route to the LTE modem subnet and nothing from the client, no ping or lookup to LTE IP or outside

Packets installed:

Snort (disable interfaces)
pfBlockerNG (disable)\
FreeRADIUS (doesn't start)
Cron

This version (2.3 built on Tue Dec 01 11:48:28 CST 2015) dosen't show packets Installed or available at this time (1 Dec 2015, 20:23 GMT). I want to uninstall some or all of them and nothing.

Some more info i can put here?

Tomorrow, maybe, i will configure the interfaces from default and report back.

EDIT: Chante Gateway monitor IP from modem IP to Google IP ~~i have Internet,~~ nevertheless no webGUI from modem (192.168.2.1).
But i have ping (dont know what i change to have it).
I have to reboot the LTE modem to check if the problem is the modem. Is not a easy access, and have battery to 3 hours.

Edit2: scratch "having internet" from wan2. I have but not from Wan2. Some rule (advanced option - Gateway) not working?
Thanks. Cya

You able to test using something other than Hyper-V? I suspect there is a problem of some sort with Hyper-V in 2.3's base OS judging by this and another report, which I haven't had a chance to dig into yet, but should soon. All the functionality you're describing works fine in general.

Hi

I have trunking wan and wan2 same physical connection using vlan in a switch to separate them, this works fine on 2.2.5.

Tomorrow i will configure interfaces without importing the 2.2.5 config and i have a AMD fusion motherboard maybe with a pcie nic + asix for wan's and integrated for lan i can test this topology.

I will be back

Why? You could be able to use one of the Load balancing method;

session based load balancing
service based load balancing
policy based load balancing

You might be also doing this compared with a ratio pending on the throughput of each Internet connection
and together with two or three fail over rules you might be getting on top a fail over set up on top.

Hi

Wan and Wan2 are different kind of Wan's one adsl and the other is LTE. The ADSL is a 2.64 max download but very stable, i need this for a home webserver and one very prioritized service in the other hand the LTE with random download speeds (500kbs to 20Mbps ) and from 7:00PM to 2:00am rarely pass 2Mbps download in a good day and they block most of the standard server incoming ports. So load balancing this is a bad experience and a probably a bad idea(?), in my opinion. I decide to use the adsl to the services and the LTE for local clients usage in failover to adsl with lots of shaping.

But if i could, your idea would be great, thanks.

Today i create a new Hyper-V switch only for the wan2 and is a no go.

Thanks

This is likely a Hyper-V issue as per thread https://forum.pfsense.org/index.php?topic=102814.0

I've noticed similar issues but haven't tested enough to report anything in detail. Ping ok, pfSense GUI ok, but no internet access on virtual machine behind virtual pfSense on Hyper-V.

Well i can access pfsense webGui and have internet through WAN but not in OPT1 (WAN2) i can ping but no internet or the Interface of the modem on the opt1.

Raul Ramos

Some more testing with the last builds in this day (12/07/2015).

With pfsense in native hardware i can have multi gateway in my case with 3 Vlan in one interface (re0). This should be a Hyper-V problem.

OK, for some reason thought i had tested disable all Checksum offload in all interfaces. Apparently not.

Disable TCP/UDP Checksum Offload and IPv4 Checksum offload in the Intel NIC 1000 PT in the host, not the interface created by the hyper-v Switch, i have network again in the OPT1 interface. No need to disable Offload on the pFsense or Hyper-v Interface Adaptor.

Always learning. I need to be more accurate in this testes next time.

Thanks. Cya
