• WebUI: Clear history or use a portable. Temporary cache bypass: Ctrl+F5, Cmd+Shift+R or new private window/incognito.
• Please report findings with steps needed to reproduce, configuration, clients, output, logs and important information below!
Important:
• Detail issues & relevant configs, logs: syslog klog 'dmesg' 'cat /tmp/var/log/messages' nvram set console_debug=1, serial.
• Firewall NAT: 'iptables -vnL' 'iptables -t nat -vnL' 'iptables -t mangle -vnL' & 'cat /tmp/.ipt'. Debug Analyze: strace tcpdump.
• Gremlins: reboot. cold boot. Reset & reconfigure not restore backup. Search Trac & discuss in forum before opening tickets.
• Include operating & wireless modes (e.g. Gateway, Router, AP, SB, WDS, Mesh) and applicable configurations to reproduce.
Example Template: |
In the portion of the new build post we are asked to gather & submit logs, operating modes, and firewall settings.
So I have a rather silly question. For those of us that are running NFTables now what would you like for us to report instead of iptables which report nothing but a list of empty chains? You get packet counts for each chain, but there are no rules listed.
For example this is what I get from R62966 for the three iptables listings:
It doens't look very helpful.
