statfull communication over 2 interfaces

S

sai

Hi,

Is that possible to establish a same communication over 2 differents interfaces?

I mean is that possible to ping a distant machine by sending ICMP requests on ethernet card and recived ICMP answers on wireless interface, for instance?

I know this senario is tricky but I think this kind of situation could occur if there is a firewall between the client and the server, for example.

So do you think FreeBSD is able to allow any statfull communication when we use a specific interfaces on input and on output?

Thanks for all ideas,

Sai

If this happens you have serious routing issues.
 
Not sure.. but it shouldn't matter. The tcp/ip stack strips off the ip addresses so higher layers don't actually look at it. As long as the sequence numbers are correct it shouldn't matter (Think tcp/ip hijack).

But there's a high probability any firewall running on that machine will flag and deny it.
