How to apply to wan interface?
I just showed you:
config device
option name 'eth0.2'
option ttl '65'
Did it work?
I Tried sysctl net.ipv4.ip_default_ttl=65 but after reboot it goes back to 64.
Did you try what I put twice above!?!?
You would add that to /etc/sysctl.conf
It will affect all interfaces.
That is what I want. How to save changes?
I just told you:
How to add that command to /etc/sysctl.conf
Can you list all steps?
Are you saying you don't know how to use the editor on the command line?
https://linux.die.net/man/1/vi
The command to enter the editor is: vi /etc/sysctl.conf
Yes sir. I don't know linux.
After adding that to vi how to exit and save?
The link to the manual will tell you.
Step 2 - find a free line
Step 3 - hit INSERT to edit
Step 4 - add sysctl line
Step 5 - hit ESC to stop editing
Step 6 :wq
to save and quit
Step 7 - reboot
(Please read the manuals and wikis provided in the future.)
Do I have enter
sysctl net.ipv4.ip_default_ttl=65 or
net.ipv4.ip_default_ttl=65
I apologize.
I mean in step 4, do I have to enter the command:
sysctl net.ipv4.ip_default_ttl=65 or
net.ipv4.ip_default_ttl=65
You're not entering any commands, your editing the file /etc/sysctl.conf
At step 4, you can see the contents of the file. If you can see the file, use the exact syntax as the other entries.
Entries in that file (as you can see) do not contain a command sysctl. So I'm not sure what you're asking.
Ok. Make sense.
Also can review below commands, will this option will work?
#from a fresh install/reset to defaults
opkg update && opkg install iptables-mod-ipopt kmod-ipt-ipopt
iptables -F
iptables -t nat -F -t mangle
iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE
iptables -t mangle -A PREROUTING -j TTL --ttl-set 65
iptables -A FORWARD -i eth1 -o br-lan -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i eth1 -o br-lan -j ACCEPT
What does this post have to do with TTL?
If your TTL issue is solved, please mark the appropriate post as the solution.
I'm not reading an off-site post. You'll need to explain.
I am working on it and let you know.
