Intermittent issues passing traffic

[ember1205]

Hi, all.

I somewhat recently installed OPNsense and have been testing with it, and I'm running into some odd behavior.

On my Android phone, I periodically can not open some web sites. If I turn off WiFi and connect initially via LTE, then I can turn WiFi back on and it will work fine. Alternatively, if I let it "spin" (clock) for a while, it will typically eventually connect but the delay is significant.

I haven't seen this behavior on other devices, so I'm looking for some ideas on how to at least troubelshoot it.

Thanks!

You haven't provided much info on your setup; to be able to assist much...

I'm experiencing similar issues. (see thread: https://forum.opnsense.org/index.php?topic=17116.0 ) - This may give some places to look at least.

I'm curious what your setup is  --  to compare; maybe a common issue or setting's we've both missed on a 'new' install.

There isn't much to share... Nothing has really been done to the firewall beyond the most basic of settings. There's a LAN port (connected to a small gigabit switch), a WAN port (directly attached to the cable modem), and only a couple of firewall rules in place to allow a couple of inbound connections to a particular machine that I run.

DHCP is provided "elsewhere" with the firewall being identified as both the gateway and the DNS server. No DNS services running on it directly, so everything is done via the default methods that the FW uses in that scenario.

The one change I have made since posting this is that I was previously pointing to my DHCP device to do DNS (and it was forwarding from there). ONLY my Android phone has had this issue, and I haven't noticed it reoccur since making the DNS change (so far).
