I suspect this might be the nvram variables for isolation misbehaving. Can you reproduce with a reboot? V3.0.5 is going to do more than validation on the variables for isolation

Personally I'm wondering if the nvrams are null/empty prior to YazFi
 
Jack Yaz said:
OK so it's good another device can connect (and presumably internet etc works fine). Which version of YazFi are you running?

What error does the TV display when trying to join?

Do you have DNSFilter set in the normal LAN? If not, I wonder if the Panasonic doesn't like its DNS being force re-routed. You could test by setting FORCEDNS to false.

Another thing to try would be "forgetting" the network on the TV and re-entering details.

Hi Jack

The error while trying to connect is a never ending circle rather than a blue tick signifying a successful connection. "A home network is available but connection to the internet is not possible. The gateway dosent respond."No I have no DNS filter . Forcedns makes no difference. The panasonic TV provides you with all Network SSIDs when connecting - you choose the one to connect to - there is no option to forget it. I did re-enter parameters manually - no difference

For the sake of testing, you can try to reset your TV back to factory defaults. :)

That will 'forget' the network properly.

I have narrowed it down by looking at connections. When I connect to my 5.1 network on 192.168.2.240 - I see port 53 ( DNS ESTABLISHED on address 192.168.2.240 - router) . Connectivity to network is fine. When I connect to 5.1 Guest and Gateway is 192.168.4.240 IP address- 192.168.4.75 in connections I see Port 53 - ASSURED address 192.168.2.240 ( router ) BUT NOT ESTABLISHED. So its a DNS issue as to why its not connecting to internet.

Can you send me the diagnostics from YazFi please in a PM? Option d in the menu
 
Generating YazFi diagnostics...
YazFi: Diagnostics saved to /tmp/YazFi.tar.gz.enc with passphrase 7dcmgjtkyis5qgxmjy2n7wbs5ebzwaoq

just rename file back to original

BTW Sorry misled you- After refreshing connections I do indeed get Port 53 with ESTABLISHED status. So its not that at all,

I wonder if the TV is trying to access something else which is blocked by YazFi but not the normal network. Can you run the below 2 commands on the router and then monitor syslog while you attempt to connect the TV to the YazFi network please? These will log all traffic coming from the TV

Code: 
iptables -I FORWARD -s 192.168.4.75 -j LOG
iptables -I INPUT -s 192.168.4.75 -j LOG

OK so I see DNS traffic, and your diagnostics look good on that. I need to see what this is for though...

EDIT: it's for netbios
 
This is with my standard 5.1 Ghz network connected- IP address of TV is 192.168.2.82 - and connection to Internet is OK

OK, try just the INPUT rule:
Code: 
iptables -I INPUT -s 192.168.4.75 -j LOG
iptables -D FORWARD -s 192.168.4.75 -j LOG

We can ignore forwarding since YazFi doesn't restrict traffic out to the wider world, only to the router itself and your LAN.

It looks like it's still struggling to talk with NetBIOS - note don't re-apply YazFi settings after running the quick fix. New quick fix:

Code: 
iptables -D YazFiINPUT -i wl1.1 -p udp --dport 137 -j ACCEPT
iptables -I YazFiINPUT -i wl1.1 -m multiport -p udp --dports 137,138 -j ACCEPT

After you run the quick fix, can you send the output of

Code: 
iptables -S YazFiINPUT

A quick search reveals this may also related to multicast traffic and/or NetBIOS. Allowing the ports 137 and 138 are the first steps (covered by the last quick fix)
I'll research what can be done for multicast
 
Code: 
joescian@RT-AC5300:/tmp/home/root# iptables -S YazFiINPUT
-N YazFiINPUT
-A YazFiINPUT -i wl1.1 -p udp -m multiport --dports 137,138 -j ACCEPT
-A YazFiINPUT -i wl1.1 -p udp -m multiport --dports 137,138 -j ACCEPT
-A YazFiINPUT -i wl1.1 -p udp -m multiport --dports 137,138 -j ACCEPT
-A YazFiINPUT -i wl1.1 -p udp -m udp --dport 53 -j ACCEPT
-A YazFiINPUT -i wl1.1 -p tcp -m tcp --dport 53 -j ACCEPT
-A YazFiINPUT -d 192.168.2.3/32 -i wl1.1 -p tcp -m multiport --dports 80,443 -j ACCEPT
-A YazFiINPUT -i wl1.1 -p udp -m multiport --dports 67,123 -j ACCEPT
-A YazFiINPUT -i wl1.1 -j YazFiREJECT
-A YazFiINPUT -i wl0.1 -p udp -m udp --dport 53 -j ACCEPT
-A YazFiINPUT -i wl0.1 -p tcp -m tcp --dport 53 -j ACCEPT
-A YazFiINPUT -d 192.168.2.3/32 -i wl0.1 -p tcp -m multiport --dports 80,443 -j ACCEPT
-A YazFiINPUT -i wl0.1 -p udp -m multiport --dports 67,123 -j ACCEPT
-A YazFiINPUT -i wl0.1 -j YazFiREJECT
 
still not connecting to the network jack

Jack- when I run 1st rule I get

joescian@RT-AC5300:/tmp/home/root# iptables -D YazFiINPUT -i wl1.1 -p udp --dpor
t 137 -j ACCEPT
iptables: Bad rule (does a matching rule exist in that chain?).

Looks like a line break has crept in. Anyway, your YazFiINPUT looks OK for now. I can't test this since I don't have a device affected, but can you try
Code: 
iptables -I YazFiINPUT -i wl1.1 -d 239.255.255.250 -j ACCEPT

I might need to add a config option to allow multicast if this turns out to be the problem
