Hi !
need your help for solving this issue
l have a router on one of ours sites ( can call it site B with lan address 193.10.24.0/24 )
l have a default route 0.0.0.0 0.0.0.0 192.168.10.195 (192.168.10.195 is the default gateway on Head Office SITE A)
all my hosts in others site use the same configuration and can use ressources in the site A (lan 192.168.10.0/24 is the site A lan , and all application servers, database and others ressources are on this LAN )
Internet is also configured to be shared with all sites ( a default route is configured in 192.168.10.195 to send internet request to my public gateway : 0.0.0.0 0.0.0.0 41.191.83.2 (it's an example !!)
My problem with site B host is that, they can reach all devices in the main site (site A ), and others sites hosts. we can make RDP sessions and ping them too from site A; they can use the application and databases. but they can't go to internet...
when i dit a traceroute from site B router (192.168.24.195 ) to a public IP ( yahoo.fr ou any public IP ) the router doesn't go firstly to the default gateway on site A and secondly to Site A public wan gateway (41.191.83.2 )
traceroute doesn't give anything.
l'm very confused , and don't know why my router on site B doesn't send unknow ip to default gateway and my users can't access on internet too !
please see below my current config on site B.
ps : site A router have a route set to join site B , there is no problem on this side and all others ressources are reachable.

Hi,
Can site A (the head office) reach the Internet?
Can you post site A config router connecting to Internet?

Hi Reza
site A can reach internet without any problem
that's the same connexion we use to share internet for all ours branches
The Routeur on site A is a LOOP-E1 CSU/DSU use to grant access and share ressources on head office.
This router is very basic, juste add a rout to network 192.168.24.0/24 ( Net_address : 192.168.024.000 Netmask : 255.255.255.000 Gateway : 192.168.010.018 Network Interface : 192.168.010.195 )
And a default route on this LOOP router to send others requests to the public gateway :
Net_address 0.0.0.0 Netmask: 0.0.0.0 Gateway : 41.191.83.2 Network Interface : 41.191.83.1
My sites are connected by leased line or radio link.
Here is the configuration of another site connected to internet.
Current configuration : 1027 bytes

What is strange, for me is why the traceroute on the routeur_B is not sent to the defaut gateway when i trying to ping yahoo server ?
Thanks for your help !!
