I have been working in an ISP (Internet Service Provider) for over a year. Here, I have to do so many tasks including Linux Server, Router & Switch Configuration, Pfsense configuration, customer complain receiving and solving accordingly etc. I have experience of configuring, troubleshooting email server with Postfix MTA and Dovecot. Also worked with Zimbra based mail server, DNS server, DHCP server, Squid Proxy Server, FTP Server etc. I have worked with Cisco routers and switches with the VPN tunneling, GLBP, OSPF, EIGRP, LACP etc. I’m also experienced with Mikrotik router with configuring IPSec VPN, GRE tunnel, Dual WAN load balancing, auto fail-over, bandwidth controlling, access control, blocking websites etc. I would love to work in a co-operative environment among the employees where opportunities come to implement new things as well as developing old one.
