Hi Yutaka, Thanks for your reply. I now have the following configuration: -Pip-to-listen-on:443 ADMIN=admin@oce.. DGROOT="/DeleGate/" DELAY=reject:0,unknown:0 SERVER=https AUTHORIZER=-ntht HTTPCONF=methods:* STLS="fsv,fcl,sslway -cert lib/cert.crt -key lib/cert.key" MOUNT="/* https://destination_ip/* via=other-ip-of-delegate-server" REACHABLE=destination_ip:443 RELIABLE="*" The setup is as follows: IIS (destination ip) - (other-ip-of-delegate-server) delegate (ip-to-listen-on) - client In IIS windows integrated authentication (NTLM) is enabled. Still, when connecting to delegate, I'm unable to connect. The logfile shows: 09/04 09:59:33.97 [2444] 3+1: REQUEST - GET / HTTP/1.1^M 09/04 09:59:33.97 [2444] 3+1: *** / => destination_ip/ *** 09/04 09:59:33.97 [2444] 3+1: REQUEST +M destination_ip/ HTTP/1.1^M 09/04 09:59:33.98 [2444] 3+1: ----NTHT accept 0 MO=1 UT=0 09/04 09:59:33.98 [2444] 3+1: ----NTHT_accept(0,53,53) ss=0 09/04 09:59:33.98 [2444] 3+1: ####cred name=NT AUTHORITY\SYSTEM 09/04 09:59:33.98 [2444] 3+1: ====NTLM Start 09/04 09:59:33.98 [2444] 3+1: SOCKET recv(41)=0 error=0 [0.000] TCP AF_INET :1228 << :1227 09/04 09:59:33.98 [2444] 3+1: ## SSLway FCL S-C:64/1 C-S:713/1 (WIN) 08:59:33.982 [2444] send(346) = -1+0 errno=10058 [1728] 09/04 09:59:33.98 [2444] 3+1: ## got SIGPIPE [1] in HTTP: (WIN) 08:59:33.982 [2444] +++EPIPE[53] fflushTIMEOUT() for EOF 09/04 09:59:33.98 [2444] 3+1: ClientEOF: request-EOF-7 [53 53] 330 8000 1 09/04 09:59:33.98 [2444] 3+1: HCKA:[0] closed -- d:by client(request EOF-7) 09/04 09:59:33.98 [2444] 3+1: disconnected [53] -@[ip]hostname:31199 (0.328s)(0) Is there something wrong in my setup / configuration or did I miss anything? Any help would be appreciated. In your documentation I don't find anything about the -Enh option.
