Question

Hi

I have 2 RUT955 and use MPLS VPN.

I also want to build an IPsec between the two.

Now I get the error message: error writing to socket: permission denied.

even if I try with traceroute to reach the IP of the other router. There I get the message permission denied.

All other IP I can ping and reach via traceroute.

Can it be caused by any firewall?

I'm using the latest firmware.

Answer 1

I found this setting.
The broadcast address is that of the other router.
Is traffic blocked here?
How can I change the broadcast address or the mask of the mobile connection? Or is this done via the provider?

Hi,

Regarding to changing the Broadcast IP address if you used 192.0.214.14 as host address the next will be broadcast
that would be 192.0.214.15 when your'e using subnet  /30.

It's already clear that the next address is Broadcast.
I get the IP xxx.0.214.14, mask 255.255.255.252 and broadcast (xxx.0.214.15) address from the provider.
My remote station now has exactly the broadcast address (xxx.0.214.15) as WAN IP. Ok
