Hello Clarence,
you would need to provide some more information about your setup,
ip addresses on interfaces , what is your pf.conf etc...
In your experia ( I believe they are android)
you can download the hurricane electric network tools (HE network
tools) (a free app to run rudimentary network diagnostic commands,
such as ping traceroute dns lookup tests to identify the problem
associated with your connection when using openBSD..
that would help you diagnose the source of the connectivity problems
you are having...
Hope this helps

Hello,
I recently setup a home network as followings (Just for fun):
ISP <----> openbsd router (version 6.6 Stable) <-------> gigabits
switch (TP-Link TL-SG1008D) <-----> linksys ea8300 (with wireless)
everything works except that I can't use my sony xperia tablet to
access internet using the wireless function provide by the
linksys-ea8300.
When I replace the openbsd-router and switch with another wireless
router, I can use my sony xperia to access the internet. Does any
one try this before ?
If yes, please let me to know how you do it. Thanks.

I totally agree with the suggestion by @Tom above!
Another good tool for Android is 'fing', it will give you access to
Traceroute and Ping functions on your Xperia.
The first thing to try would be to see if the Xperia can communicate
with the gateway (OpenBSD router) then if that is successful public IP
addresses. If something strange is going on you can further run
Traceroute to narrow down where the issue is occurring.
On the OpenBSD side, it could be a number of things like PF rules,
routing, NAT but without further information it is basically a guess
as to what it could be.
Just to elaborate here a little; you can run the 'tcpdump' program on
OpenBSD to give you more information.
To get started: man tcpdump
If you want to see where the packets from the Xperia are traveling then
something like:
tcpdump -eni (inside_interface) host (ip_of_Xperia)
For debugging PF rules a good start is to use: tcpdump -eni pflog0 <-
you can further narrow things down by using the 'action' option eg.
'block' / 'allow'
Hope this helps a little more :-)
