HDLC over STUN

[pax_2111]

Hi,

I am new to serial tunneling. I was wondering whether the following is possible. I want to connect 2 routers through HDLC using the serial interfaces on each with STUN.

r1 ---- s0 ---- r2 ---- STUN ---- r3 ---- s0 ---- r4

I configured STUN between r2 and r3 and it's up. I configured the seial interfaces of r1 and r2 and they are up. But the ping fails.

The STUN config is quite simple.

stun peer-name 8.8.8.8

stun protocol-group 1 basic

interface Serial0

no ip address

no ip directed-broadcast

encapsulation stun

clockrate 64000

stun group 1

stun route all tcp 7.7.7.7

Will this work or am I missing something?

thanks

Yes, it should work. Can you run debugs on the routers? If you can, run debug ip icmp on R1 and R4. Also, run debug stun packet on R2 and R3.
