Hello All,

i have a Host H with 3 virtual server
i can access from a VPS to the internet , and with NAt rule (Via Shorewall) i can access from Internet to the 3 VPS
i want that all the 3 VPS can communicate between them.
i can't do a tcp connection from a VPS to an other , in my shorewall log in the Host, i have this error :
kernel: Shorewall:FORWARD:REJECT:IN=venet0 OUT=venet0 SRC=192.168.7.185 DST=192.168.7.152 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=48986 DF PROTO=TCP SPT=47559 DPT=25 WINDOW=5840 RES=0x00 SYN URGP=0

some body here have the solution ?

thanks in advance

As I understand you just set REJECT-rule for ip-forwarding from one VE to another... To be sure, please give the command on host:

# iptables -L -nv

If so, just remove this rule.

Thanks for your answer
i m using a shorwall firewall
i have this in my default policy, my Host is fw

net all DROP info
fw all ACCEPT
loc all ACCEPT
loc venet ACCEPT #
venet all ACCEPT
all all REJECT info

And it doesn't work.

But if i replace the last line with
all all ACCEPT
it work. but this rule is very permissive

i triyed many combination ... no good result !

Perhaps the problem is that venet0 isn't a real ethernet interface ? so we can't do this simply ...



Thanks.

Is it possible for you to post here the output of
# iptables -L -nv

here.
Shorewall is based on iptables and I want to see exact iptables rules, that Shorewall has set.

Thanks!

This is quick analysis.

Chain FORWARD (policy DROP 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination
 3595  331K eth0_fwd   all  --  eth0   *       0.0.0.0/0            0.0.0.0/0
 4006 2992K venet0_fwd  all  --  venet0 *       0.0.0.0/0            0.0.0.0/0
    0     0 eth1_fwd   all  --  eth1   *       0.0.0.0/0            0.0.0.0/0
    0     0 Reject     all  --  *      *       0.0.0.0/0            0.0.0.0/0
    0     0 LOG        all  --  *      *       0.0.0.0/0            0.0.0.0/0           LOG flags 0 level 6 prefix `Shorewall:FORWARD:REJECT:'
    0     0 reject     all  --  *      *       0.0.0.0/0            0.0.0.0/0


You can see the string "Shorewall:FORWARD:REJECT" - that is what in your error message, thus packets are droped here. Therefore the packet isn't catched by the rule "venet0_fwd". Look at it:

Chain venet0_fwd (1 references)
 pkts bytes target     prot opt in     out     source               destination
  199 15876 dynamic    all  --  *      *       0.0.0.0/0            0.0.0.0/0           state INVALID,NEW
 4006 2992K venet2all  all  --  *      eth0    0.0.0.0/0            0.0.0.0/0
    0     0 venet2all  all  --  *      eth1    0.0.0.0/0            0.0.0.0/0


Really! out equals eth0 and eth1, but in our case, when two VEs speake, out must equals venet0 too.

Perhaps because venet0 isn't a real network's interface. it's a virtual one.
So i must do other thinks ...

I have also tried to do the same and added the venet line in the /etc/shorewall/interfaces also but the shorewall just terminates with an error message that reads:

ERROR: Invalid zone (venet) in record "venet venet0 detect routeback"


Where did I go wrong? This is basically based on the 3-interface setup of shorewall. find below the output of iptables -L -nv:

Let me clear my situation to explain why webmin is not the way to go. I tried yum install webmin in the hostnode, but reported that there is no such maches.

I am using 3-interface home network with eth0 (internet), eth1 (local) and eth2 (dmz). The host node of the machine serves as firewall and also a gateway to the local and dmz (connected to voip server by a crossove cable). Now the problem whatever I change in the shorewall configurations as stated above and other changes, my voipserver connected to eth2 could not access the termination server as well as the VEs are not accessible.

Does anyone has any clue with the existing stuff?
