I again have a potential easy question for this community. I have a SRX220 which is connected to an ISP via
ge-0/0/0 {
unit 0 {
family inet {
address xxx.xxx.xxx.253/24;
}
}
}
routing-options {
static {
route 0.0.0.0/0 next-hop xxx.xxx.xxx.1;
}
}
security-zone Internet {
interfaces {
ge-0/0/0.0 {
host-inbound-traffic {
system-services {
ping;
}
}
}
}
}
When sending a PING to the static IPV4 address "xxx.xxx.xxx.253”, I do receive a response from my SRX220.
Last week I ordered and installed a 2nd internet line, connected via an independent VDSL modem and static IPV4s as well. My goal with that line is to run it as load balancing and fallback solution. As a first step, I just wanted to connect the modem with my SRX220 and receive a PING response from outside.
The network is: yyy.yyy.yyy.176/29 and the modem itself has the IPV4 address yyy.yyy.yyy.177. When connecting a simple PC to that modem and assigning the static IPV4 yyy.yyy.yyy.178 and the gateway yyy.yyy.yyy.177, I do receive a PING response from that PC when calling it from outside by “PING yyy.yyy.yyy.178”.
I then moved the PC cable to my SRX220 and configured:
ge-0/0/1 {
unit 0 {
family inet {
address yyy.yyy.yyy.178/29;
}
}
}
security-zone untrust2 {
interfaces {
ge-0/0/1.0 {
host-inbound-traffic {
system-services {
ping;
}
}
}
}
}
Unfortunately, I do not receive any PING answer when calling “PING yyy.yyy.yyy.178” from the outside. I’m sure it is my mistake and I guess it is something about the missing modem gateway, however, can anybody help and advise me about the mistake I have made?
Thank you.
