ISP connection setup problem

[xtacy]

Hi!
3 NICs:
ETH00 is for my home LAN
ETH01 uses PPPoE connection and works fine with ZS.
ETH02 uses only Dyn.IP and nothing else just connect and go (like PnP)! Doesnt work with ZS at all! But If i connect this ISP’s ethernet cable direct to my PC (bypassing ZS) internet on that PC works perfectly which means ZS is a problem.

So the question is how to setup my second internet connection via ETH02 properly?

Tried to do many things such as using only second ISP alone but no success. ZS refuses to manage it. I guess ZS didnt realize that ETH02 is WAN and manage it like an usual LAN.

thanx.

using ZS 1.0.beta13 on CF

Added:
this is the route table:

Destination Netmask Type Metric Gateway Interface Flags State Source
10.0.0.1 255.255.255.255 Host 0 none ppp0 UH Up Auto
10.33.169.0 255.255.255.128 Net 0 none ETH01 U Up Auto
10.54.29.0 255.255.255.0 Net 0 none ETH00 U Up Auto
188.230.20.0 255.255.254.0 Net 0 none ETH02 U Up Auto
DEFAULT GATEWAY 0.0.0.0 Net 0 188.230.20.1 ETH02 UG Up Auto
DEFAULT GATEWAY 0.0.0.0 Net 0 none ppp0 U Up Auto

also added NAT for ETH02
Still no changes. ZS ignore my 2nd ISP. In the NET BALANCER ETH02 fail the Failover test:

00:49:17 +++ Testing across the gateway NetG (Interface: ppp0) +++
00:49:17 [74.125.39.105] : Success (Round Trip Time: 45.9 ms)

seems like my 2nd ISP is like an external router for ZS

If you ping from your ZS (utilities menu) do you get a response? Is your second ISP blocking ICMPs? Is your second ISP filtering packets depending on MAC address so that your desktop connects but your ZS fails?

Yes i do. I do get responses from google, yahoo, this site or any other alive website at all even if 1st ISP is disconnected physically. But every arp finishes with msg like:

WARNING: the host 62.149.128.154 is not directly connected on the ETH02 LAN but is reachable via
the gateway 188.230.20.1: ARP is a Layer 2 Protocol and it cannot be routed by routers!

Don’t know

No. Any connected PC works fine. I guess if I connect their cable to a simple 8ports switch all of 7 PCs connected to that swith would work fine due to ISP’s DCHP. But anyway – is it possible to change the MAC in ZS (like in WinXP)?

You mean here that you get responses from any site from the utilities ping, if the first connection is deactivated? The syntax was ambiguous that is why I am asking.
It looks like the ping from ZS is working fine. Don’t worry about the arp error, this is normal.
Could you please post here the output of the commands

ifconfig

iptables -L -v

iptables -t nat -L -v

Also a screenshot of the NetBalancer page from the web gui would be helpful.

Yes.
i mean if 1st IPS’s ethernet cable isn’t connected to ZS’s PC (not just deactivated via Network Setup).

I’m sorry about that.

that’s what i got with the only ETH02/ISP2 connected (unchecked ETH01/ppp0’s Up and reboot ZS):

Go to Netbalancer, select Inti and in the “Gateway configuration” add the 188.230.20.1 as IP address and try the pinging again.

[xtacy]

thanx, that made both connections Active at NB. And the Utils’s Ping works fine but it did b4 anyway, what’s the point?
And what if second ISP’s GW would change? Should i monitor this situation all the time?

And the next looks like a huge bug! I did the following via web interface:
1) In the Network setup – unchecked ETH01 “Up” chkbox
2) In the Network setup – unchecked PPP0 “Up” chkbox
3) Reboot ZS
After reboot in the in the Network setup ETH01 “Up” chkbox stays unchecked while PPP0 is checked on and IT IS CONNECTED!!! How’s that could happen? It looks 4me like 1st ISP’s PPPoE goes via 2nd ISP. I believe both ISPs wouldn’t thank me for that if it’s so!

[ppalias]

Point is that Netbalancer need to specifically have the gateway declared, regardless if it is declared in the routing section (which is why ping worked). Most likely (99,999%) the gateway of your ISP won’t change.
After the reboot the ppp0 is up again cause you have checked the auto start at boot in its properties.
