Open firewall to specific computer

[swerdna]

Yast --> System --> etc sysconfig editor --> Network --> Firewall --> SuSEfirewall2 --> FW_TRUSTED_NETS --> ip1.1p2.1p3.1p4,tcp

I haven't ried that myself but it should work according to the write-up, which is this:

File: /etc/sysconfig/SuSEfirewall2
Possible Values: Any value
Description:

10.)
Which services should be accessible from 'trusted' hosts or nets?

Define trusted hosts or networks (doesn't matter whether they are internal or
external) and the services (tcp,udp,icmp) they are allowed to use. This can
be used instead of FW_SERVICES_* for further access restriction. Please note
that this is no replacement for authentication since IP addresses can be
spoofed. Also note that trusted hosts/nets are not allowed to ping the
firewall until you also permit icmp.

Format: space separated list of network[,protocol[,port]]
in case of icmp, port means the icmp type

Example: "172.20.1.1 172.20.0.0/16 1.1.1.1,icmp 2.2.2.2,tcp,22"
