Move tunnel to another computer

[Parodper]

Hi,

I'm trying to move a tunnel, from one machine (A) to another (B). I set up the 6in4 in B, and removed the tunnel from A, but I can't get B to work. Both machines are in the same LAN, behind NAT. The config is the same in both machines, except for the local endpoint, which is the machine's private IP.

A worked without issue, and if I do a portscan, I can see that A still receives ICMP Request and SYN. ICMP Request from B don't get any response.

I tried unplugging A for a while, using the WAN address, and switching the Client IPv4 Address around, to see if I could invalidate whatever cache there is, but nothing worked.

Try rebooting the router.

So uh, I didn't do anything, and now it works? Sorry for the noise.

@evantkh, thanks for the tip, although I didn't get to try it.

Looks like you need to wait for NAT mapping expiration (for protocol 41) before you can use on another computer.
