Spoke to Spoke routing (VIGOR to CISCO)

Go to solution

Hi All,

I have a problem with my config, it's a hub and spoke setup with 7 spokes. The hub network address is 192.168.6.0.

I would like the spoke sites to be able to communicate to other spokes via the hub. The spoke site are vigor routers and the hub is a cisco 1842, the routing table is present on the vigors. I'm presuming it's an ACL problem but i've spent the last 3 hrs trying to figure this one out and have got no where, can anyone assist?

Also I have nat'd ports 80, 443 which work fine from outside the local lan but do not work inside? Anyone got any suggestions?

Thanks

Mark

Mark,

The configuration seems fine to me ( unless i am overlooking something ) ,

can you please elaborate more on "I put those nat changes through, couldn't ping the server from site to site though? " , also if the config is still in place , paste the out put of sh ip nat trans ,

then 

clear ip nat statistics

then 
sh ip nat statistics 

Also if possible , send me the public ip add so that I can run NMAP and see if it shows me ports open on 
public ips as desired.

Hi Manish,

Im sorted now, changed the mail to come in on the main ip and not one of the additional I asked for. All working great now, while I was at this particular site changed the network address also from 10.0.0.0 to 192.168.98.0 so all the vigor to cisco SA's all work correctly.

Thanks very much for all your help, couldn't have done it without you.

Cheers

Mark

For the spoke-to-spoke communication issue, it does sound like an ACL problem. Ensure that the ACLs on your Cisco 1842 hub are allowing traffic between the spokes and not just inbound/outbound traffic.braintree  Check that the ACLs permit traffic for the spoke networks and the appropriate protocols.

For the NAT issue with ports 80 and 443, ensure that NAT rules are configured correctly to handle both inbound and internal traffic. You might need to set up "hairpin NAT" or loopback NAT to allow internal clients to access the services using public IPs.

Double-check the ACLs and NAT settings on your Cisco router, and make sure the configurations are applied correctly.
