SSH from outside local subnet

English Network/Internet
1

Hello all,

I guess I’ve missed something in opening my suse box up for SSH.

IP of server is 10.10.10.4/24

I can SSH to it from 10.10.10.2/24 but not from 10.20.20.2

I’ve done
iptables -X
iptables -F

iptables-save

This is what I see from iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

In my hosts.allow I added:

sshd : ALL : ALLOW

Anyone have any ideas why I can’t ssh from another network? Just to note, I can reach the box with pings from the 10.20.20.0 network, I’m just newbie with linux :slight_smile:

And what about the router between those two networks?

IMO also to be considered and perhaps more to the point since both are private networks have you constructed routing tables for each network to “see” the other(one or both are not the Default Gateway of the other)?

Right… start with basic tests. Can you ping? Can you get there via
other TCP or UDP-based services? Did this ever work? Can you access
anything else on the box? Does a LAN trace on the destination side even
see packets from the source side? When you try to SSH (or ping, or
netcat, or whatever) what error comes back?

Good luck.
