Hello All,

Can you please look at my configuration and suggest your ideas.

My Current network details:-

Br_router- HQ router- Etisalat ISPCloud for internet

- Branch ofc router and HQ are connected with a Leased line .

-From HQ router Internet link is connected from ISP on a Fast ethernet port.

-Between Branch office and HQ Eigrp 1 is configured and able to ping till HQ.

-From HQ default route is configured towards ISP ip address to access internet from router.

-After this HQ router is able to ping Outside WWW world.

*- To allow Branch office also to access the same HQ internet i have configured PAT with access-list allowing Branch ofc network on HQ router , but still i can not able to access/ping internet.

Configuration:-

HQ router:-

Interface ser 0/3/1 (leasedline ->Branch)

ip address 172.30.1.10 255.255.255.0

no shut

interface fa 0/1 ( ISP connection)

ip add 194.170.133.126 255.255.255.252

no shut

Router Eigrp 1

(default route for ISP link)

access-list 1 permit 172.30.0.0 0.0.255.255

access-list 1 permit 192.168.20.0 0.0.0.255

BR office router:-

ip add 172.30.1.20 255.255.255.0

router eigrp 1

redistribute connected

network 172.30.1.0

no auto-summary

After configuring above configuration i am not able to ping 194.170.133.125 ip address which is the ISP end ip from Branch office router and not able

to ping www world.

at Branch off router , my trace is not crossing beyond 172.30.1.10.

at the other end at HQ router i am able to ping 194.170.133.125 and ping www world .

Thanks for all your support.
