Hi Boryan,
ur explanation on my prob is what it should be but to clarify some things:
202.184.41.0/ 255.255.255.255.0
192.168.206.0/255.255.255.240
and the 2 vlan routers are connected by another vlan router...the 2 PCs are
in two different locations...
1st PC
2nd PC
[192.168.202.1]
[192.168.206.1 ] down link
[202.184.41.41] up link
|
|
Router 1 Router
Router 2
+--[192.168.202.14]------[192.168.201.14]----------------[192.168.206.14]--+
i am able to ping all routers and the PC 192.168.206.1 except
202.184.41.41....i must be able to access 202.184.41.41 because this address
has IPv6 connectivity from a local tunnel broker...so there will be a tunnel
from PC 1 to PC 2 later....thanks a lot !
PS: i know this a netfilter list...but i have been getting responses
here....

Hi,
its Diana again...after setting "route add -net 202.184.41.0/24 gw
192.168.202.14", i still could not ping 202.184.41.41 ( the PC )....i
could ping the 202.184.41.0 add
i also set the "route add -net 202.184.41.0/24 gw 192.168.206.1" but it
says network unreachable....
Lets try to analyze what information regarding your network setup, you gave
till now (from all your e-Mails).
First e-Mail:
^^^^^^^^^^^^^^^
I need help!! My VLAN IP is 192.168.202.1. I can ping another PC with the
VLAN IP of 192.168.206.1 but i can't ping the 202.184.41.41 address in
that PC. Am i supposed to do some sort of routing configuration? I am
using FC3 as my OS. What am i supposed to do to ping 202.184.41.41? Thanks
At least from my point of view, your network setup at this stage looks
like:
1st PC 2nd PC
[192.168.202.1]<------------------------>[192.168.206.1 | 202.184.41.41]
You have two PCs:
- first one configured with an IP address of 192.168.202.1
- second one with two IP addresses - 192.168.206.1 and 202.184.41.41
You said packets are able to travel between end 192.168.202.1 and end
192.168.206.1. In order this to be able to work, both ends need to be
located on a same subnet (like 192.168.0.0/16) ... OR ... in two different
subnets, while both ends have an explicit routing entry for reaching each
other.
Second e-Mail:
^^^^^^^^^^^^^^^
yup 202.184.41.41 is configured in the same PC as 192.168.206.1
the subnet mask is 255.255.255.240
The new info is that either 202.184.41.41 or 192.168.206.1, is inside a
subnet with net mask 255.255.255.240:
So one of the subnets below sure exists:
202.184.41.32/255.255.255.240
192.168.206.0/255.255.255.240
Third e-Mail:
^^^^^^^^^^^^^^^
thanks for the reply...the gateway for my 192.168.202.1 PC is
192.168.202.14 which is the vlan router which enables me to ping the
192.168.206.1 vlan address...for the route in the network device control,
the destination network is 192.168.206.0, the subnet mask 255.255.255.240
and the gateway as 192.168.202.14...this is what i have done so far...i am
not too sure on how i should configure a default gateway ot static
route...
Now, there is a new player in the picture - 1st PC's (probably default)
Gateway/router which has an IP address 192.168.202.14 and some kind of link
to 192.168.206.1.
1st PC 2nd PC
[192.168.202.1] [192.168.206.1 | 202.184.41.41]
| Gateway |
+---[192.168.202.14 | ???.???.???.???]---+
Good thing is that one of the subnets is clear now -
192.168.206.0/255.255.255.240
The bad thing - it is not clear how Gateway is able to route packets from
192.168.202.1 to 192.168.206.1. Probably Gateway has a second interface
within the subnet of 192.168.206.1 ... OR ... both Gateway and 2nd PC are
directly connected while using explicit routes?
Not clear is also what you mean by: "...for the route in the network device
control, the destination network is 192.168.206.0, the subnet mask
255.255.255.240 and the gateway as 192.168.202.14...".
Fourth e-Mail:
^^^^^^^^^^^^^^^
no, the VLANs are not connected to the same router...the vlan router for
192.168.206.1 is 192.168.206.14
the router is Cisco...
Okey, it is getting worse. You are sure that 192.168.202.1 and
192.168.206.1 (what I understand by "the VLANs") are not connected to the
same router. The picture looks completely different now:
1st PC 2nd PC
[192.168.202.1] [192.168.206.1 | 202.184.41.41]
| Router 1 Router 2 |
+--[192.168.202.14] ?? [192.168.206.14]--+
My questions are: Is the last schema matching your network topology? If
true, how are Router 1 and Router 2 connected with each other? If not,
could you try to write a simple schema description as the ones from above?
