[nos-bbs] rip broadcasts in jnos

[jerome schatten]

OK Bob, thanks!

Now, how to tell if his router is using CGNAT? Is there a way to find out? Mine is more or less a standard Hytron CPE box and it has always just worked. His situation, as I understand it, seems more like a streaming service -- his box has his TV stuff and other services on it, and he has to contact Rogers to do things like turn on/off DMZ, and access other network functions. 

So, this would be a completely different problem set if ipip is being blocked at the Rogers' end -- he would have to decide how and if he really wants to proceed. 

So, back to my question #2 -- How to find out if ipip is being blocked at Rogers? Maybe it's sensible to call Rogers and ask them <g>?

Best,
jerome

His router has to pass IPIP/IPENCAP, that is  tcp/ip protocol 4 to receive RIP, that is a prerequisite. If his router can't be setup as such, he can install DD-WRT in it if that is available for the chipset in this router.

Make sure that his ISP is not using Carier-Grade NAT (CGNAT) as that is blocking incoming IPIP (and more) at the ISP level.  If he is behind CGNAT or the problem with his router can't be solved, he can sign up

to 44Net connect at https://connect.44net.cloud/ of ARDC  and use a WireGuard VPN tunnel, that gives a tunnel 44 address. If his WireGuard tunnel is working he can use that tunnel 44 address instead of his

commercial address in his portal entry. In that way he bypasses all problems and can receive IPIP / IPENCAP and so RIP.

His set-up in jnos is identical to mine, and his set-up at the portal is identical to mine. I receive the rip broadcasts, and he does not. Both of us are using raspberry pi's, and both are running headless (ssh in to start jnos).
