Lan 2 Lan connection setup
Can anybody advise me? We've got two SRX5308 on different sites (A+B). The sites are currently connected using VPN but this is unstable. The provider of the fibre connection has made a direct connect...
There's no reason the vpn should be unstable unless there's other routing issues, which I think there are possibly a lot (network loops and more) with the current layout.
What are you trying to accomplish because I think there's a much, much simpler way to do this as there are a lot of 'just not right' connections in that diagram.
Currently the connection between A and B are active over port 4 of the fibre modem. Discard Site-B's backup ISP (Ziggo), it's not there (mistake). We want to have site A and B connected over the lan2lan connection. Site B will use Site A gateway to the internet. That's all. It would be great if the corp VLAN's could be intact, that means that we don't have to renumber (IP) Site B.
By lan2lan connection, are you referring to a vpn tunnel over the fibre connections?
So basically you're just wanting all traffic from site B to go out via site A's connection, correct? Vlans intact if possible?
Thanks for your reply!
No, it's a lan2lan connection (no VPN tunnel). When connecting to modem port 4 on site B it recieves an IP of site A (that works already).
Yes all trafic from B must go to site A, so that:
1) B uses A to go to the internet (site B's own current internet connection is going away, just leaving the direct connection between the modems)
2) Corp netwerk site A must be able to connect to Corp B -> 2 different VLAN's, corp A VLAN 178, corp B VLAN 225, both sites managed VLAN's are 1, both have an additional VLAN for the guest WIFI network: Site A VLAN 165, site B VLAN 235. For the IP range of teh VLAN's see my picture in the other post.
3) Yes VLAN's intact if possible!!! :) it saves renumbering servers, printers and a lot more....
Okay, so something isn't right here. What are these fibre modems? Because if they connect to the Internet, either they are providing some sort of tunnel between the sites or something else is because you cannot just route packets over the Internet like that unless everything has static Internet IPs.
