sctplab / sctp_proxy Goto Github PK

I was writing here to see if you would consider consulting us on the setup of an SCTP proxy server? My email is nukuuk at gmail.com. If you are interested

I try to use the proxy listening on 127.0.0.1 with DNAT configured with iptables, but connexion from client failed.
I build the network with 3 VMs in the same private network 192.168.179.0/24 : client (.133)---proxy (.128) ----server (.134)

server command : sudo ncat --sctp -l 192.168.179.134 38412

proxy command : proxy -4 -i 2048 -o 1024 -L 192.168.179.128:38412 -X 192.168.179.128 -S 192.168.179.134:38412
proxy iptables conf : sudo iptables -t nat -I PREROUTING -p sctp -d 192.168.179.128 -j DNAT --to-destination 127.0.0.1:38412
sudo iptables -t nat -I POSTROUTING -p sctp -s 127.0.0.1 -j SNAT --to-source 192.168.179.128

client command : sudo ncat --sctp 192.168.179.128 38412 --> Ncat: Connection refused.

Here is the pcap on proxy :

Any idea about this issue for checksum unverified ?
