[DSL] Anyone having ping/tracert and firewall based issues?

I'm tech savvy enough to know it's neither my modem, router, and network configuration causing this as I have friends outside my network pinging and testing it from their end.

For some odd reason my network became like the time I once had Bell DSL service, the thing stops accepting pings and port forwards, then simply rejects connections when you try to host game servers (dedicated ones on a simple file for example).

The internet works fine sure, but it's like something is blocking people from pinging and connecting to me directly, but at the same time I opened my firewall and all for a brief moment just to test them pinging me (allowed ping request via router, disabled port scan and dos protection briefly), I even used DMZ for that matter.

Example: One of my friend ran a tracert. The moment it hits my modem's ip address (ISP given ip address) it hits a 100% packet loss and no response.
Then later on it's the router giving no response (after changing a few things).

My Sagemcom modem doesn't seem to have advanced settings to turn off ping blocking, or even advanced firewall settings for that matter, so it's very hard to know if it's that or something else.

My Netgear router picked up 'service blocked' (in the admin logs) and various ip address popping up, and I have no idea if it's a DoS attack or such.

EDIT2: Okay i switched the modem's dns to google (8.8.8.8) and now it's says im connected to the internet in general. But I might still have ping blocking issue when someone pings me.

It would be on whichever device is actually doing the PPPoE connection, look for the ping-block there.

No there is no options to disable ping blocking on it, I checked it.

Settings -> Internet / Wireless / Network / Games and Application / Advanced Settings
Advanced settings only shows WAN mode and Services tab.
Network only shows DHCP / Port Forwarding / DMZ / uPnP / and DynDNS.

Ping block would have to be in the internet settings, but nope.
I only get 2 tabs:
Internet (login interface) and DNS (changing dns only)

The options given here looks like a 'basic' settings, and there is no obvious way to go into the 'advanced' stuff.

Name: Bell Connection Hub
Firmware Version: FAST2864_v67428
Rescue Version: FAST2864_v7637F
Hardware Version: 2864-000000-002

The firmware explains why it's so dumbed down.

It's the only VDSL modem Teksavvy (but I know it's really Bell) accepts.

After I reconfigured the ip to organize my network better, I still get 100% packet loss when I use various sites to ping my isp given ip address.

Tracert shows the route to my isp, but then suddenly the network shows signs of latency when it enters bell's servers.

Now when it hits my ip, it stops responding.

EDIT: I think my network is being DDosed.

Googling some of the ip shows honeypot reference.

I turned on ping request accepted but it didn't show anything new.
But still the ping still gets refused by the modem.

Due to the uselessness of my modem, I can't even see proper statistics on how many unique ip addresses are attempting to connect to my modem through the internet, without relying on outside tools.

Looking up more information, it seems factory reset might fix it but... It clears out the username and password on the machine.
