[Serusers] Routing issues with SER

I'm having issues with routing in my SER. Does anybody have a sample ser.cfgfile to share with me to start testing inside my machine first ? Please, see the error message bellow: db1:/etc# sipsak -U -I -e 5 -s sip:doug@db1.net:5060 -vv registering user doug0... received: SIP/2.0 483 Too Many Hops Via: SIP/2.0/UDP localhost.localdomain:32859;received=127.0.0.1;rport=32859 From: sip:doug0@db1.net:5060;tag=22aab1db To: sip:doug0@db1.net:5060;tag=b27e1a1d33761e85846fc98f5f3a7e58.5645 Call-ID: 581611995(a)localhost.localdomain CSeq: 1 REGISTER Server: Sip EXpress router (0.9.6 (i386/linux)) Content-Length: 0 Warning: 392 127.0.0.1:5060 "Noisy feedback tells: pid=6637 req_src_ip= 127.0.0.1 req_src_port=5060 in_uri=sip:db1.net:5060 out_uri=sip:db1.net:5060via_cnt==18" error: didn't received '200 OK' on register (see above). aborting db1:/etc#
