Re: PCAnywhere and IPCHAINS
Thanks for your reply.
I saw some examples using both portfw and autofw, that's why I was trying
I've removed autofw but it still failed.
My machine details:
server FW (IP: x.x.x.a interfaces: x.x.x.x/29 and 192.168.1.0/24 ipchains running
pc C (IP: x.x.x.b PCAnywhere client)
server P (IP: 192.168.1.2 it behinds server A, PCAnywhere host)
So my externalip would be x.x.x.a and internal IP is 192.168.1.2. On server
allowed both TCP and UDP connection for ports 5631 and 5632. When I tried to
to server P from pc C, I always get timed out.
From server FW's syslog, I can see the following line:
Jan 3 09:49:36 FW kernel: Packet log: input ACCEPT eth0 PROTO=17 x.x.x.b:45770
L=30 S=0x00 I=27892 F=0x0000 T=127 (#48)
I've done "echo 1 > /proc/sys/net/ipv4/ip_forward" as well.
My route table is as the following:
Destination Gateway Genmask Flags Metric Ref Use Iface
x.x.x.net 0.0.0.0 255.255.255.248 U 0 0 0 eth0
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
0.0.0.0 x.x.x.gw 0.0.0.0 UG 0 0 0 eth0
I'm not sure what have I still missed out here?
