Need help setting up a zyxel device as Internet gateway.Device is a P-870HN-51D.
Note: When i plug directly into the adsl router with a laptop I can browse the internet fine.
My core switch plugs directly into the Zyxel router.
Cisco4500 [Fa4/47]-> Zyxel router [Fa1]
Cisco config:
-interface vlan11 --ip address 10.150.11.2 255.255.255.0 -interface Fa4/47 --switchport access vlan 11
Switchport IP on the zyxel - 10.150.11.110
When I configure the above, the link will simply not work, and I am unsure where its breaking.. It should be rather simple..
I cannot even get to the 10.150.11.110 address on the zyxel device unless i add a static return route on it as such; 10.0.0.0 255.0.0.0 via 10.150.11.2
When I test the connectivity (by browsing the internet), I am doing so from user vlans, i.e;
10.150.17.0 10.150.18.0 etc.
I feel like this is going to be a rather simple fix but I don't have a CCNA/CCNP and im sure theres some basic info that im missing.
Any help would be appreciated. |

You need to make a static route that covers all the subnets you got on the Cisco switch. Since the default route is already used for the internet. Depending on your 4500 setup, you might get away with changing the subnetmask on the P870 to 255.0.0.0 |

I missed putting in this further information;
When I didn't have ANY static routes set on the device, I could not get to the Zyxel's IP address at all. I then added the route 10.0.0.0 255.0.0.0 via 10.150.11.2 and the device became accessible. I still cant browse the internet though from anything downstream of the device. |

You need to have a default route that points at the Prestige LAN IP. |

ip route 0.0.0.0 0.0.0.0 10.150.11.110 10 |

If your routes are correct it should work as long as NAT is enabled on the ZyXEL device. |

Frankly I'm quite confused about your setup. A diagram and config screenshots would help. |

Also does the hosts on you try to ping from get that default route?
What does the ip configuration look like on a host? |
