Hello all, Is there any way to add src-adress to a list which incoming request to my pppoe router ttl is greater than 1 or 2 or as i wish. For example i have PPPoE users they connect via home wireless router so this router connection ttl should be 1 to connect my PPPoE server router, and if this router sharing internet from its lan ports to another router, second router ttl should be 2, so i want to make a src-address list for those routers which are sharing internet to another router.
No, they probably have a ttl of 64 or 128, etc and decrement from there as they cross hops
Let me rephrase,
There is option in filter rules that you can check the TTL under advanced tab and then add src address to address list, but what I meant with the “No” is that they will most probably not have a TTL of 1 or 2, but higher value, i.e. 64 / 128 depending if they cross any hops
TTL usually start at 64, 128 etc and “decrement” as it crosses hops
pppoe packets themself aren’t routable, aren’t IP and have no ttl. You can not see if they bridge pppoe to another device. (probably mac address they send changes)
The encapsulated IP packet inside pppoe has a TTL set by to remote client, and is decremented by 1 for each routing hop in between. Bridging pppoe isn’t a routing hop
What is your question?
