Reach the modem on the WAN port

Superman

Maybe it's because of the network range & subnet you are on. I'm on the 192.168.1.x/24 (255.255.255.0) range so my modem is on the same subnet. If you are on a different range (ie: 10.0.0.x) you can probably get there, but you'll have to do so differently…I'll leave that to the networking experts to explain, or for you to google...

I thought the same….
I'll do some test soon...

Thanks!

Seems like you have the option check to block private networks (had this same problem with a test firewall behind a real firewall)
in the web interface go to "interfaces" > "wan" uncheck "Block private networks" that should do it for ya.

Hope it helps.

I uncheck "Block private networks" and "Block bogon networks" but I can't reach the modem.

As you use pppoe I doubt that it's doable as everything gets routed into the pppoe wan encapsulation and this way bypasses the modem inside the "pppoe tunnel". :-\

But I can Ping the Modem… this is trange... But I can't open the web page...

Emab

Ok, reset all…
I have done a mistake...

so...
My modem has IP: 192.168.222.254 mask 255.255.255.252 (/30)
I connect to internet via WAN interface via PPPoE.
My Lan IP is 192.168.0.x 255.255.255.0
My OPT IP is 192.168.1.x 255.255.255.0

In SSH in the pfSense PC, if I try to ping:

# ping 192.168.222.254
PING 192.168.222.254 (192.168.222.254): 56 data bytes
^C
--- 192.168.222.254 ping statistics ---
3 packets transmitted, 0 packets received, 100% packet loss

Now I try to add the IP to the WAN interface in the same subent of the modem:

# ifconfig fxp0 inet 192.168.222.253 netmask 255.255.255.252

Now I can ping the modem:

# ping 192.168.222.254
PING 192.168.222.254 (192.168.222.254): 56 data bytes

4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max/stddev = 0.445/0.594/0.959/0.212 ms

If I do a tcpdump:

# tcpdump host 192.168.222.254
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on fxp0, link-type EN10MB (Ethernet), capture size 96 bytes

and do a Ping to the modem in the Guiweb interface, I have:
in web interface:

Ping output:

PING 192.168.222.254 (192.168.222.254) from 82.54.197.133: 56 data bytes

--- 192.168.222.254 ping statistics ---
3 packets transmitted, 0 packets received, 100% packet loss

and in SSH (tcpdump):

11:55:00.868368 IP host133-197.pool8254.interbusiness.it > 192.168.222.254: ICMP echo request, id 46596, seq 0, length 64
11:55:01.869104 IP host133-197.pool8254.interbusiness.it > 192.168.222.254: ICMP echo request, id 46596, seq 1, length 64

And I can't reach the web gui of the modem…

What's wrong?
I've to add a rule to the firewall? or a static route?

Someone could help me?

Thanks!

on interfaces wan
uncheck this option:

Block private networks
When set, this option blocks traffic from IP addresses that are reserved for private
networks as per RFC 1918 (10/8, 172.16/12, 192.168/16) as well as loopback addresses
(127/8). You should generally leave this option turned on, unless your WAN network
lies in such a private address space, too.

I'be tryied yet. but this can't resolve mu problem…

If I try to reach the admin page of the modem I have in TCPDUMP:

# tcpdump host 192.168.222.254

What I can do else?

No help? :(

the probleme is pppoe that is boulding a tunnel between pfsense and youre isp
when pppoe is active the modem is completly pased and youre pings end up at the isp end of the pppoe tunnel not at the modem

I understand this…
But I can reach the modem using the SSH in the pfSense...so I think that should be possible to route some pachet from the lan interface directly to the WAN interface (where I added the IP addres in the modem LAN) and not in the PPPoE tunnel...
But I'm not so skilled in BSD networking...

Some help?

Hi,
make sure you have NAT on WAN IF, if not you will need to add static routes in the modem for your LAN and opt's.

Could you please explain me what I've to do? Thanks!
