Re: Can SQUID change the destination address from ip to hostname?

Thanks, i'll try.
Better will be to make Squid listen also to a SOCKS5 port. I know there was a project years ago, seems to be broken and never implemented.

The real problem is that all proxifiers tools use ip:port as destination at first instance (redsocks, ts-warp, for example).

SOCKS5 works with 1st level tcp, so send ip addresses, i need some tool, or Squid workaround, which can force a reverse dns. I know, it's quite impossible if a ptr record is not found in dnses, but... i try..
