Let me repeat what 'You' wrote: Um, isn't the gateway the same as the
router interface?
Now let me point out what I'm used to seeing.
The network 63.226.233.136 has 8 IP addresses reserved for it. The first
and the last are reserved (both are for broadcast, network and broadcast).
The first host is network +1 the last is network +6. This is what I'd
expect:
---+ +-+ +--------+
ISP|------| |---| Host 1 |
---+ |H| +--------+
|U| :
|B| +--------+
| |---| Host 5 |
+-+ +--------+
This is what you've told me:
---+ +----------+ +-+ +--------+
ISP|--| MyRouter |----| |---| Host 1 |
---+ +----------+ |H| +--------+
|U| :
|B| +--------+
| |---| Host 5 |
+-+ +--------+
Normally the IP's between the Myrouter and the ISP's routers would be
one network and the IP's between Myrouter and the rest of the network
would be another. That is unless Myrouter can do firewalling with
bridging instead of routing. My network at home is setup in a similar
way. I have a 24 network between My router and the ISP and I have a
192.168.x.x, 172.16.x.x, and a 10.x.x.x network behind my router.
Myrouter does Network Address Translation (or IP Masquerading).
