question
Interesting event happened yesterday
(My computer) issued to the Internet 224.0.0.2 (all routers) request which my firewall blocked.
This is the first time this has happened
I do not have my routers hooked up to the net
I run console cable not Ethernet cable to my routers
This may be right in front of my nose but I am stumped
Does any one have a clue -
Thanks

part 2 - this is strange
RouterA#sh x25
X.25 software, Version 3.0.0.
0 configurations supporting 0 active contexts
VCs allocated, freed and in use: 0 - 0 = 0
VCs active and idle: 0, 0
XOT software, Version 2.0.0.

I DID NOT ACTIVATE X 25 on my router.
There is no one here other than me who knows anything anout Cisco
Something (application) activated this

I'm not sure what you mean by "(My computer) issued to the Internet 224.0.0.2"... As for "sh x25" I believe you don't need to activate X.25 in order to see that output. AFAICS there's nothing out of ordinary here.

Dmafti
My computer issued the multicast request, my firewall block the request (224.0.0.2) out to the internet or my local network. (This means that an application tried to hook to, or get information from routers that are in the network. "Zone Alert has block access to the Internet from multicast 224.0.0.2 from your computer (ICMP)" It is not unusual to see " Gator client (172.1.2.2) was denied access to the Internet" but I have not seen
a class D address denied to or from the firewall.
I have not started studying for remote access, I do not know if X25 is on by default. Strange I see it (x25) in the 'sh run' on router A, but it is not on the 'sh run' on router B, yet when I do the 'sh x25' on B, the output is the same as A.

Problem #1
I have a firewall (zone alarm) that blocked an all router multicast FROM my computer. Its not supposed to do this. Here is an example of what Zone Alarm does
The firewall has blocked Internet access to your computer (HTTP) from 213.97.74.18 (TCP Port 3768) [TCP Flags: S].
Time: 4/16/02 10:32:46 AM
In the case I am talking about, 224.0.0.2 was blocked FROM my computer TO the Internet
Problem #2
On my routers x25 is enabled, I didn't enable it.
Solution
This may be a virus but I do not know where to start

Thanks kbani
I checked the "applications" on ZA to find out if there was a new app installed recently, did not find one.
Why would my computer arbitrarily send out a multicast?
Why did my router have x25 in the running config when I did not enable it?
